is mercury a gas giant
Today, the use of mercury in medicine has greatly declined in all respects, especially in developed countries. Mercury-containing compounds are also of use in the field of structural biology. A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. [125] The convention was signed on 10 October 2013. Best known is mercury(II) chloride, an easily sublimating white solid. Most thermometers now use pigmented alcohol instead of mercury, and galinstan alloy thermometers are also an option. Time on Mercury. Several other first row transition metals with the exception of manganese, copper and zinc are also resistant in forming amalgams. With continuing exposure, a fine tremor develops and may escalate to violent muscular spasms. A day on Mercury lasts 59 Earth days. One example is Hg2+3(AsF−6)2.[41]. Starting as a gas giant accounts for the disproportionate size of its metallic core and for Mercury’s density. Mercury(II) salts are a rare example of simple metal complexes that react directly with aromatic rings. [109], Sediments within large urban-industrial estuaries act as an important sink for point source and diffuse mercury pollution within catchments. [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]. Astronomy. In Lamanai, once a major city of the Maya civilization, a pool of mercury was found under a marker in a Mesoamerican ballcourt. Do you believe mercury was gas giant earlier?give reasons? Mercury thermometers are still widely used for certain scientific applications because of their greater accuracy and working range. In 2005, China was the top producer of mercury with almost two-thirds global share followed by Kyrgyzstan. In March 2005, the EPA promulgated a regulation[129] that added power plants to the list of sources that should be controlled and instituted a national cap and trade system. [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. Skin tanner containing a low-pressure mercury vapor lamp and two infrared lamps, which act both as light source and electrical ballast.

"[139], Products containing mercury were banned in Sweden in 2009.[140][141]. . [99], Artificial lakes may be contaminated with mercury due to the absorption by the water of mercury from submerged trees and soil. Mercury(II) is the most common oxidation state and is the main one in nature as well. [5] The latter sometimes occurs naturally as metacinnabar. It has a large metallic core, made of solid or liquid iron. [35] Worker health in functioning mines is at high risk. [36], Mercury exists in two oxidation states, I and II. Initially, the Spanish Crown's mines in Almadén in Southern Spain supplied all the mercury for the colonies. Mercury fulminate is a detonator widely used in explosives.[5]. 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. 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. Preindustrial deposition rates of mercury from the atmosphere may be about 4 ng /(1 L of ice deposit). Heating of mercury, or of compounds of mercury that may decompose when heated, should be carried out with adequate ventilation in order to minimize exposure to mercury vapor. [105][106], The tobacco plant readily absorbs and accumulates heavy metals such as mercury from the surrounding soil into its leaves. It is commonly known as quicksilver and was formerly named hydrargyrum (/haɪˈdrɑːrdʒərəm/ hy-DRAR-jər-əm). It started with the same basic chemical composition as the other planets with the same general proportion of iron to rock to gaseous materials. Historically, one of the largest releases was from the Colex plant, a lithium isotope separation plant at Oak Ridge, Tennessee. If long-period gas giant planets are found in the TRAPPIST-1 system, then it could help resolve a longstanding debate about the formation of our own Solar System's gas giant planets. 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. In 2008, Denmark also banned dental mercury amalgam,[139] except for molar masticating surface fillings in permanent (adult) teeth. A complete explanation of mercury's extreme volatility delves deep into the realm of quantum physics, but it can be summarized as follows: mercury has a unique electron configuration where electrons fill up all the available 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, and 6s subshells. [47] Nevertheless, thiomersal has been removed from, or reduced to trace amounts in all U.S. vaccines recommended for children 6 years of age and under, with the exception of inactivated influenza vaccine.[48]. Unlike organocadmium and organozinc compounds, organomercury compounds do not react with water. You fall through this abyss for a very, very long time. Fish and shellfish have a natural tendency to concentrate mercury in their bodies, often in the form of methylmercury, a highly toxic organic compound of mercury. [55], Some transit telescopes use a basin of mercury to form a flat and absolutely horizontal mirror, useful in determining an absolute vertical or perpendicular reference. The general belief is that these gas giants formed first as icy and rocky planets similar to the terrestrial planets Mercury, Venus, Earth and Mars. 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]. Mercury is a heavy, silvery-white liquid metal. [110] The strong affinity of mercury for carbon rich sediments has also been observed in salt marsh sediments of the River Mersey mean of 2 mg/kg up to 5 mg/kg. [94], Natural sources, such as volcanoes, are responsible for approximately half of atmospheric mercury emissions. When added to neon filled tubes the light produced will be inconsistent red/blue spots until the initial burning-in process is completed; eventually it will light a consistent dull off-blue color.[65]. The plant operated in the 1950s and 1960s. [135] In July 2007, the European Union also banned mercury in non-electrical measuring devices, such as thermometers and barometers. 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. This use allows a new uncontaminated electrode to be available for each measurement or each new experiment. DMSA was able to increase the excretion of mercury to a greater extent than NAP. [118][119] A study has shown that acute exposure (4–8 hours) to calculated elemental mercury levels of 1.1 to 44 mg/m3 resulted in chest pain, dyspnea, cough, hemoptysis, impairment of pulmonary function, and evidence of interstitial pneumonitis. The World Health Organization, OSHA, and NIOSH all treat mercury as an occupational hazard, and have established specific occupational exposure limits. Mercury remains in use in scientific research applications and in amalgam for dental restoration in some locales. 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. Mercury poisoning can result in several diseases, including acrodynia (pink disease), Hunter-Russell syndrome, and Minamata disease. Occupational exposure has resulted in broad-ranging functional disturbance, including erethism, irritability, excitability, excessive shyness, and insomnia. Satisfactory alternatives to Hg in products are When dropped, elemental mercury breaks into smaller droplets which can go through small cracks or become strongly attached to certain materials. [136], Norway enacted a total ban on the use of mercury in the manufacturing and import/export of mercury products, effective 1 January 2008. We breathe it and fly planes right through it with no trouble. 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. Population-based biomonitoring also showed that mercury concentration levels are higher in consumers of seafood and fish meals.[68]. It is commonly known as quicksilver and was formerly named hydrargyrum (/ haɪˈdrɑːrdʒərəm / hy-DRAR-jər-əm). For example, Williston Lake in northern British Columbia, created by the damming of the Peace River in 1968, is still sufficiently contaminated with mercury that it is inadvisable to consume fish from the lake. If scientists would like to study the core of a gas giant roughly the size of Neptune or Uranus, they need look no further than Mercury. The farther away they are, the more time it takes to make one trip around the Sun. [110] The highest mercury concentrations were shown to occur in and around the city of London in association with fine grain muds and high total organic carbon content. [89] It is also used as a disinfectant. [133], In the European Union, the directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (see RoHS) bans mercury from certain electrical and electronic products, and limits the amount of mercury in other products to less than 1000 ppm. Some facial creams contain dangerous levels of mercury. Graphic showing o ur best understanding of giant planet interiors in 2003. Because mercury and methylmercury are fat soluble, they primarily accumulate in the viscera, although they are also found throughout the muscle tissue.

The terrestrial planets are Mercury, Venus, Earth, and Mars. I got to thinking, and wondered whether Mercury might be such an object. [102] Due to health concerns (see below), toxics use reduction efforts are cutting back or eliminating mercury in such products. [15], The mines in Almadén (Spain), Monte Amiata (Italy), and Idrija (now Slovenia) dominated mercury production from the opening of the mine in Almadén 2500 years ago, until new deposits were found at the end of the 19th century. Mercury is a chemical element with the symbol Hg and atomic number 80. Mercury is made up of distinct layers, similar to Earth. [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. In polarography both the dropping mercury electrode[60] and the hanging mercury drop electrode[61] use elemental mercury. In 2008, Norway's Minister of Environment Development Erik Solheim said: "Mercury is among the most dangerous environmental toxins. To be considered a gas giant, the planet has to be made up of mostly gas, be located in the outer area of the solar system, and have a mass that is ten times that of Earth. mercury This metal or one of its… By far the largest use of mercury[52][53] in the late 20th century was in the mercury cell process (also called the Castner-Kellner process) where metallic sodium is formed as an amalgam at a cathode made from mercury; this sodium is then reacted with water to produce sodium hydroxide.

Credit: NASA Coined by the science fiction writer, James Blish, this is another term used to describe the 4 outermost planets in the Solar System: Jupiter, Saturn, Uranus and Neptune. 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. The terrestrial planets are Mercury, Venus, Earth, and Mars. I got to thinking, and wondered whether Mercury might be such an object. [102] Due to health concerns (see below), toxics use reduction efforts are cutting back or eliminating mercury in such products. [15], The mines in Almadén (Spain), Monte Amiata (Italy), and Idrija (now Slovenia) dominated mercury production from the opening of the mine in Almadén 2500 years ago, until new deposits were found at the end of the 19th century. Mercury is a chemical element with the symbol Hg and atomic number 80. Mercury is made up of distinct layers, similar to Earth. [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. In polarography both the dropping mercury electrode[60] and the hanging mercury drop electrode[61] use elemental mercury. In 2008, Norway's Minister of Environment Development Erik Solheim said: "Mercury is among the most dangerous environmental toxins. To be considered a gas giant, the planet has to be made up of mostly gas, be located in the outer area of the solar system, and have a mass that is ten times that of Earth. mercury This metal or one of its… By far the largest use of mercury[52][53] in the late 20th century was in the mercury cell process (also called the Castner-Kellner process) where metallic sodium is formed as an amalgam at a cathode made from mercury; this sodium is then reacted with water to produce sodium hydroxide. Gas giants are sometimes known as failed stars because they contain the same basic elements as a star.
