Scientists have theorized that the crumpled surface and lobe-shaped scarps (cliffs and ridges) were formed when the planet cooled and shrank. [120] Acute exposure to mercury vapor has been shown to result in profound central nervous system effects, including psychotic reactions characterized by delirium, hallucinations, and suicidal tendency. It started with the same basic chemical composition as the other planets with the same general proportion of iron to rock to gaseous materials. Being a soft metal, mercury forms very stable derivatives with the heavier chalcogens.

When it formed, its core was a liquid iron dynamo. "[21], The ancient Greeks used cinnabar (mercury sulfide) in ointments; the ancient Egyptians and the Romans used it in cosmetics. Graphic showing o ur best understanding of giant planet interiors in 2003. The purest of these was gold, and mercury was called for in attempts at the transmutation of base (or impure) metals into gold, which was the goal of many alchemists. [17] The "first" emperor of China, Qín Shǐ Huáng Dì—allegedly buried in a tomb that contained rivers of flowing mercury on a model of the land he ruled, representative of the rivers of China—was killed by drinking a mercury and powdered jade mixture formulated by Qin alchemists (causing liver failure, mercury poisoning, and brain death) who intended to give him eternal life. Like ZnS, HgS crystallizes in two forms, the reddish cubic form and the black zinc blende form. The patio process and later pan amalgamation process continued to create great demand for mercury to treat silver ores until the late 19th century. 1 Answer chandramohanPanakkal I had a quick look at modelling this and noticed there would seem to be critical point that if the planet crossed it then the process would start to accelerate exponentially. The most toxic forms of mercury are its organic compounds, such as dimethylmercury and methylmercury. Jupiter's composition is mainly hydrogen and helium. Choose Mercury as your Gas Supplier and get Natural Gas for your home or business and enjoy great Energy deals when you are a Gas and Electricity customer Environmental releases and disposal of mercury are regulated in the U.S. primarily by the United States Environmental Protection Agency. Several other first row transition metals with the exception of manganese, copper and zinc are also resistant in forming amalgams. [137] In 2002, several lakes in Norway were found to have a poor state of mercury pollution, with an excess of 1 µg/g of mercury in their sediment. [29], Beginning in 1558, with the invention of the patio process to extract silver from ore using mercury, mercury became an essential resource in the economy of Spain and its American colonies. Occupational exposure has resulted in broad-ranging functional disturbance, including erethism, irritability, excitability, excessive shyness, and insomnia. Likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Thus, industries that release high concentrations of mercury into the environment agreed to install maximum achievable control technologies (MACT). Once fully cooled, the dense metallic core was left in a weak but permanent magnet state. A 2001 study measured mercury levels in 12 indoor sites chosen to represent a cross-section of building types, locations and ages in the New York area. Mercury is a chemical element with the symbol Hg and atomic number 80. Several laws give the EPA this authority, including the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, and the Safe Drinking Water Act. Species of fish that are high on the food chain, such as shark, swordfish, king mackerel, bluefin tuna, albacore tuna, and tilefish contain higher concentrations of mercury than others. Iron is an exception, and iron flasks have traditionally been used to trade mercury. [43] They arise by a process known as biomethylation. Lighting containing mercury can be bombarded/oven pumped only once. [24], Alchemists thought of mercury as the First Matter from which all metals were formed. It comes from hydrargyrum, a Latinized form of the Greek word ὑδράργυρος (hydrargyros), which is a compound word meaning "water-silver" (from ὑδρ- hydr-, the root of ὕδωρ, "water," and ἄργυρος argyros "silver") – since it is liquid like water and shiny like silver. Long-term, low-level exposure has been associated with more subtle symptoms of erethism, including fatigue, irritability, loss of memory, vivid dreams and depression. Mercury(II) chloride (also known as mercuric chloride or corrosive sublimate) was once used to treat syphilis (along with other mercury compounds), although it is so toxic that sometimes the symptoms of its toxicity were confused with those of the syphilis it was believed to treat. It is commonly known as quicksilver and was formerly named hydrargyrum (/ haɪˈdrɑːrdʒərəm / hy-DRAR-jər-əm). who discovery Mercury?define period of rotation and period of revolution.is Mercury considere tobe a gas giant Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination. [128], The United States Clean Air Act, passed in 1990, put mercury on a list of toxic pollutants that need to be controlled to the greatest possible extent. Population-based biomonitoring also showed that mercury concentration levels are higher in consumers of seafood and fish meals.[68]. Mercury and most of its compounds are extremely toxic and must be handled with care; in cases of spills involving mercury (such as from certain thermometers or fluorescent light bulbs), specific cleaning procedures are used to avoid exposure and contain the spill. Some facial creams contain dangerous levels of mercury. Detailed Synopsis: Mercury began in the same swirling gas cloud as the rest of the planets, moons and other objects in our solar system. well, airy. The first edition of the Merck's Manual featured many mercuric compounds[45] such as: Mercury is an ingredient in dental amalgams. Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. The richest mercury ores contain up to 2.5% mercury by mass, and even the leanest concentrated deposits are at least 0.1% mercury (12,000 times average crustal abundance). It’s a gas giant, composed mostly of hydrogen and helium NEPTUNE Neptune is the farthest planet in our Solar System and also the fourth-largest 21 Sometimes, reviewing concepts is a good idea. [36], Mercury exists in two oxidation states, I and II. Far beneath Jupiter's atmosphere is a gigantic ocean of liquid metallic hydrogen, which would look and behave like mercury except that hydrogen has 60 percent the density of water. 15918 I was reminded today of the idea of a chthonian planet. Review of its safety has found that cinnabar can lead to significant mercury intoxication when heated, consumed in overdose, or taken long term, and can have adverse effects at therapeutic doses, though effects from therapeutic doses are typically reversible. [93] Protocols call for physically merging smaller droplets on hard surfaces, combining them into a single larger pool for easier removal with an eyedropper, or for gently pushing the spill into a disposable container. This use allows a new uncontaminated electrode to be available for each measurement or each new experiment. Mercury’s magnetic field is still active. They form tetrahedral complexes with other ligands but the halides adopt linear coordination geometry, somewhat like Ag+ does. They believed that different metals could be produced by varying the quality and quantity of sulfur contained within the mercury. Mercury does not have any moons. [105][106], The tobacco plant readily absorbs and accumulates heavy metals such as mercury from the surrounding soil into its leaves. [33]:47 Several other countries are believed to have unrecorded production of mercury from copper electrowinning processes and by recovery from effluents. For this reason, Uranus and Neptune are … The impact scaring on the surface gives testament to Mercury's gas free past. I got to thinking, and wondered whether Mercury might be such an object. [46] Thiomersal is metabolized to ethyl mercury. Some medical thermometers, especially those for high temperatures, are filled with mercury; they are gradually disappearing. The mercury-containing organohalide merbromin (sometimes sold as Mercurochrome) is still widely used but has been banned in some countries such as the U.S.[91]. ", "Two States Pass First-time Bans on Mercury Blood Pressure Devices", "Title 21—Food and Drugs Chapter I—Food and Drug Administration Department of Health and Human Services Subchapter D—Drugs for Human Use Code of federal regulations". This study found mercury concentrations significantly elevated over outdoor concentrations, at a range of 0.0065 – 0.523 μg/m3. [20], In November 2014 "large quantities" of mercury were discovered in a chamber 60 feet below the 1800-year-old pyramid known as the "Temple of the Feathered Serpent," "the third largest pyramid of Teotihuacan," Mexico along with "jade statues, jaguar remains, a box filled with carved shells and rubber balls. [50] Mercury compounds are found in some over-the-counter drugs, including topical antiseptics, stimulant laxatives, diaper-rash ointment, eye drops, and nasal sprays. [94], Natural sources, such as volcanoes, are responsible for approximately half of atmospheric mercury emissions. Cleaning porous surfaces and clothing is not effective at removing all traces of mercury and it is therefore advised to discard these kinds of items should they be exposed to a mercury spill. [126], In the United States, the Environmental Protection Agency is charged with regulating and managing mercury contamination. The outer shell is only about 300 or 400 miles thick. Edlich, Richard F.; Rhoads, Samantha K.; Cantrell, Holly S.; Azavedo, Sabrina M. and Newkirk, Anthony T. CS1 maint: BOT: original-url status unknown (, standard conditions for temperature and pressure, membrane cell or diaphragm cell technologies, United States Environmental Protection Agency, Mercury-Containing and Rechargeable Battery Management Act, "Atomic weights of the elements 2013 (IUPAC Technical Report)", "Magnetic Susceptibility of the Elements And Inorganic Compounds", Random House Webster's Unabridged Dictionary, "Why is mercury liquid? [12][13] Sodium amalgam is a common reducing agent in organic synthesis, and is also used in high-pressure sodium lamps. The miniaturized Deep Space Atomic Clock is a linear ion-trap-based mercury ion clock, designed for precise and real-time radio navigation in deep space. . [102] Due to health concerns (see below), toxics use reduction efforts are cutting back or eliminating mercury in such products. Electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet light, which then causes the phosphor in the tube to fluoresce, making visible light. "Chapter 3: Manufacturing Processes Involving Mercury. Mercury has another problem.It is near Sun and the solar wind is also blowing out the atmosphere. Mercury can be absorbed through the skin and mucous membranes and mercury vapors can be inhaled, so containers of mercury are securely sealed to avoid spills and evaporation. There is also the red planet, called Mars, where ast… [132] Cement kilns that burn hazardous waste are held to a looser standard than are standard hazardous waste incinerators in the United States, and as a result are a disproportionate source of mercury pollution. I was investigating exoplanet data and noticed that some gas giants near stars show signs of evaporating due to being too close to the star. Our universe is an inconceivably vast space that contains billions of heavenly bodies, and even then, most of outer space is completely empty! Concave horizontal parabolic mirrors may be formed by rotating liquid mercury on a disk, the parabolic form of the liquid thus formed reflecting and focusing incident light. A year on Mercury lasts 88 Earth days. Gaseous mercury is used in mercury-vapor lamps and some "neon sign" type advertising signs and fluorescent lamps. The terrestrial planets are Mercury, Venus, Earth, and Mars. induces disproportionation to Hg2+ and elemental mercury. If heated, it is a colorless, odorless gas. Toxic effects include damage to the brain, kidneys and lungs. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. The coefficient of volume expansion is 181.59 × 10−6 at 0 °C, 181.71 × 10−6 at 20 °C and 182.50 × 10−6 at 100 °C (per °C). The average was 0.069 μg/m3. [35], Abandoned mercury mine processing sites often contain very hazardous waste piles of roasted cinnabar calcines. Most of the remaining radioisotopes have half-lives that are less than a day. After all, air is the gas we all know and love. Such liquid-mirror telescopes are cheaper than conventional large mirror telescopes by up to a factor of 100, but the mirror cannot be tilted and always points straight up. Historically, one of the largest releases was from the Colex plant, a lithium isotope separation plant at Oak Ridge, Tennessee. [56][57][58], Liquid mercury is a part of popular secondary reference electrode (called the calomel electrode) in electrochemistry as an alternative to the standard hydrogen electrode. Other elements that do not readily form amalgams with mercury include platinum. The following methods try to transform the planets into something useful for settlers that will move to their satellites. Satisfactory alternatives to Hg in products are All four mercuric halides are known. They usually have the formula HgR2, which are often volatile, or HgRX, which are often solids, where R is aryl or alkyl and X is usually halide or acetate. When dropped, elemental mercury breaks into smaller droplets which can go through small cracks or become strongly attached to certain materials. By studying the Gas Giant planets, scientists can study how the _____. HgCl2 forms coordination complexes that are typically tetrahedral, e.g. The novel use of mercury allows very compact atomic clocks, with low energy requirements, and is therefore ideal for space probes and Mars missions. [5], It has a freezing point of −38.83 °C and a boiling point of 356.73 °C,[6][7][8] both the lowest of any stable metal, although preliminary experiments on copernicium and flerovium have indicated that they have even lower boiling points (copernicium being the element below mercury in the periodic table, following the trend of decreasing boiling points down group 12). The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. [5] The latter sometimes occurs naturally as metacinnabar. The gas giant planets in our Solar System. Because mercury and methylmercury are fat soluble, they primarily accumulate in the viscera, although they are also found throughout the muscle tissue. Water run-off from such sites is a recognized source of ecological damage. mercury cadmium telluride and mercury zinc telluride being semiconductors useful as infrared detector materials.[42]. For this reason, mercury is not allowed aboard an aircraft under most circumstances because of the risk of it forming an amalgam with exposed aluminium parts in the aircraft.[14]. Despite claims otherwise,[37] Hg(III) and Hg(IV) compounds remain unknown.[38][39]. Although this form of mercury appears to be less toxic than other forms, its use in traditional Chinese medicine has not yet been justified, as the therapeutic basis for the use of cinnabar is not clear.[49]. 05-1097)", "Oldest, dirtiest power plants told to clean up", "EPA Regulations Give Kilns Permission To Pollute", "Directive 2002/95/EC on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment", "EU bans mercury in barometers, thermometers", "Sweden may be forced to lift ban on mercury — The Local", Centers for Disease Control and Prevention – Mercury Topic, Natural Resources Defense Council (NRDC): Mercury Contamination in Fish guide, NLM Hazardous Substances Databank – Mercury, BBC – Earth News – Mercury 'turns' wetland birds such as ibises homosexual, Changing Patterns in the Use, Recycling, and Material Substitution of Mercury in the United States, https://en.wikipedia.org/w/index.php?title=Mercury_(element)&oldid=997377936, CS1 maint: BOT: original-url status unknown, Short description is different from Wikidata, Wikipedia indefinitely semi-protected pages, Articles with unsourced statements from March 2017, Wikipedia articles incorporating a citation from the 1911 Encyclopaedia Britannica with Wikisource reference, Creative Commons Attribution-ShareAlike License, Mercury Bichloride (Corrosive Mercuric Chloride, U.S.P. Although that can be considered a natural level of exposure, regional or global sources have significant effects. Preindustrial deposition rates of mercury from the atmosphere may be about 4 ng /(1 L of ice deposit). [111] These concentrations are far higher than those shown in salt marsh river creek sediments of New Jersey and mangroves of Southern China which exhibit low mercury concentrations of about 0.2 mg/kg.[112][113]. Mercuric compounds such as mercury(II) chloride or potassium tetraiodomercurate(II) can be added to protein crystals in an effort to create heavy atom derivatives that can be used to solve the phase problem in X-ray crystallography via isomorphous replacement or anomalous scattering methods. It is approximately 1% of the strength of Earth’s. Mercury reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury (spill kits also use activated carbon and powdered zinc).[11]. [63] It is also used in specialist medical care lamps for skin tanning and disinfection. Astronomy. [130] However newer data published in 2015 showed that after introduction of the stricter controls mercury declined sharply, indicating that the Clean Air Act had its intended impact. "[139], Products containing mercury were banned in Sweden in 2009.[140][141]. There are seven stable isotopes of mercury, with 202Hg being the most abundant (29.86%). [9] Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69 g/cm3 when liquid to 14.184 g/cm3 when solid. Treatment of Hg(I) compounds complexation with strong ligands such as sulfide, cyanide, etc. Currently available drugs for acute mercurial poisoning include chelators N-acetyl-D, L-penicillamine (NAP), British Anti-Lewisite (BAL), 2,3-dimercapto-1-propanesulfonic acid (DMPS), and dimercaptosuccinic acid (DMSA). Mercury and its compounds have been used in medicine, although they are much less common today than they once were, now that the toxic effects of mercury and its compounds are more widely understood. Vacuum cleaners and brooms cause greater dispersal of the mercury and should not be used. [125] The convention was signed on 10 October 2013. [64] Gaseous mercury is added to cold cathode argon-filled lamps to increase the ionization and electrical conductivity. Those low-pressure lamps emit very spectrally narrow lines, which are traditionally used in optical spectroscopy for calibration of spectral position. ", "Mercury Contamination from Historical Gold Mining in California", "Did Mercury in "Little Blue Pills" Make Abraham Lincoln Erratic? The European Union directive calling for compact fluorescent bulbs to be made mandatory by 2012 has encouraged China to re-open cinnabar mines to obtain the mercury required for CFL bulb manufacture. You fall through this abyss for a very, very long time. Mercury(II) oxide, the main oxide of mercury, arises when the metal is exposed to air for long periods at elevated temperatures. Because this configuration strongly resists removal of an electron, mercury behaves similarly to noble gases, which form weak bonds and hence melt at low temperatures. The "hot Jupiters" found in orbits of a few days are much hotter than the surface of Mercury. In the United States, non-prescription sale of mercury fever thermometers has been banned since 2003. [109], Sediments within large urban-industrial estuaries act as an important sink for point source and diffuse mercury pollution within catchments. Stable derivatives include the chloride and nitrate. HgCl2−4. Preeminent is mercury(II) sulfide, HgS, which occurs in nature as the ore cinnabar and is the brilliant pigment vermillion. An f shell poorly screens the nuclear charge that increases the attractive Coulomb interaction of the 6s shell and the nucleus (see lanthanide contraction). [104], A serious industrial disaster was the dumping of mercury compounds into Minamata Bay, Japan. For another thread I was looking at what happens when a planet loses hydrogen. Mercury is unlikely to be close enough to be a chthonic planet. Mercury, like other planets ... rocky worlds should be more common than the more massive gas giants. Thousands of prisoners were used by the Luo Xi mining company to establish new tunnels. [28] Mercury(II) selenide (HgSe) and mercury(II) telluride (HgTe) are also known, these as well as various derivatives, e.g. [30] Mercury deposits were discovered in the New World, and more than 100,000 tons of mercury were mined from the region of Huancavelica, Peru, over the course of three centuries following the discovery of deposits there in 1563. 1.1% from mercury production, mainly for batteries. In polarography both the dropping mercury electrode[60] and the hanging mercury drop electrode[61] use elemental mercury. [89] It is also used as a disinfectant. Your services 22 MERCURY Mercury is the closest planet to the Sun and the smallest one in the Solar System—it’s only a bit larger than our Moon. It reverts to the elements upon heating near 400 °C, as was demonstrated by Joseph Priestley in an early synthesis of pure oxygen. The gas-giant planets Jupiter, Saturn, Uranus and Neptune in our solar system are quite different in mass, density, and in chemical composition than the inner terrestrial planets Mercury, Venus, Earth, and Mars. It is a standard in electrochemistry. A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. Jupiter and Saturn are the gas giants of the Solar System. The rule was deemed not sufficient to protect the health of persons living near coal-fired power plants, given the negative effects documented in the EPA Study Report to Congress of 1998. Mercury is the smallest planet in our solar system. The farther away they are, the more time it takes to make one trip around the Sun. [32], Mercury is extracted by heating cinnabar in a current of air and condensing the vapor. Most astronomers consider it a planet, although there was a proposal a few years ago to reclassify it to a minor planet. Many historic applications made use of the peculiar physical properties of mercury, especially as a dense liquid and a liquid metal: Others applications made use of the chemical properties of mercury: Mercury(I) chloride (also known as calomel or mercurous chloride) has been used in traditional medicine as a diuretic, topical disinfectant, and laxative. gas planet A gas giant (sometimes also known as a Jovian planet after the planet Jupiter, or giant planet) is a large planet that is not primarily composed of rock or other solid matter. Like silver, mercury reacts with atmospheric hydrogen sulfide. The element was named after the Roman god Mercury, known for his speed and mobility. Mercury’s Neighbors. However, its rate of spin was not enough to maintain the dynamo and it quickly cooled. Emerging out the bottom, the pressure is now intense, and it's starting to get quite warm, and there's nothing but the dark abyss of ever-denser hydrogen gas beneath you. It is small and rocky. [115] Mercury present in prey fish accumulates in the predator that consumes them. Television and film writers, too, have found the planet an ideal location for storytelling. Another mercury compound, merbromin (Mercurochrome), is a topical antiseptic used for minor cuts and scrapes that is still in use in some countries. Blue mass, a pill or syrup in which mercury is the main ingredient, was prescribed throughout the 19th century for numerous conditions including constipation, depression, child-bearing and toothaches. Mercury is the closest planet to the Sun and due to its proximity it is not easily seen except during twilight. Effects and symptoms of mercury poisoning, CS1 maint: multiple names: authors list (. [100][101], Mercury also enters into the environment through the improper disposal (e.g., land filling, incineration) of certain products. One example is Hg2+3(AsF−6)2.[41]. In 2005, China was the top producer of mercury with almost two-thirds global share followed by Kyrgyzstan. [95], Recent atmospheric mercury contamination in outdoor urban air was measured at 0.01–0.02 µg/m3. [59] Last, but not least, the triple point of mercury, −38.8344 °C, is a fixed point used as a temperature standard for the International Temperature Scale (ITS-90).[5]. But take another look at Jupiter and Saturn—or pictures of them. [34] In China, prison labor was used by a private mining company as recently as the 1950s to develop new cinnabar mines. The gas and ice giant planets take longer to orbit the Sun because of their great distances. It has a large metallic core, made of solid or liquid iron. It is used in some thermometers, especially ones which are used to measure high temperatures. In 2008, Minnesota became the first state in the United States to ban intentionally added mercury in cosmetics, giving it a tougher standard than the federal government. Scientists refer to the atmospheres of Saturn and Jupiter as being more “polluted” because they have larger percentages of heavy metals such as methane and ammonia. Known as Nessler's reagent, potassium tetraiodomercurate(II) (HgI2−4) is still occasionally used to test for ammonia owing to its tendency to form the deeply colored iodide salt of Millon's base. Indicative of its tendency to bond to itself, mercury forms mercury polycations, which consist of linear chains of mercury centers, capped with a positive charge. Hydrogeochemical release of mercury from gold-mine tailings has been accounted as a significant source of atmospheric mercury in eastern Canada. The stability of the 6s shell is due to the presence of a filled 4f shell. In one small study including 11 construction workers exposed to elemental mercury, patients were treated with DMSA and NAP. This process is called biomagnification. Usually the salt is dissolved in water to produce a brine. However, a large heavy atmosphere with strong wind currents and weather patterns under great pressure will account for these features. Mercury’s mean density is the second-highest in the Solar System, ... As a gas giant (aka. Mercury dissolves many metals such as gold and silver to form amalgams.
