Mercury is a heavy, silvery transition metal with the distinctive feature of being liquid near ordinary room temperature. It has a filled 5d shell and commonly forms +1 and +2 compounds, with covalent character more prominent than in many lighter metals. Mercury has been used in instruments, electrical devices, and gold extraction, but many uses have declined because its vapor and several compounds are highly toxic.
It is a heavy, silvery-white metal; a rather poor conductor of heat, as compared with other metals, and a fair conductor of electricity. It easily forms alloys with many metals, such as gold, silver, and tin, which are called amalgams. Its ease in amalgamating with gold is made use of in the recovery of gold from its ores. The most important salts are mercury chloride (corrosive sublimate - a violent poison), mercurous chloride (calomel, occasionally still used in medicine), mercury fulminate, a detonator widely used in explosives, and mercuric sulfide (vermilion, a high-grade paint pigment). Organic mercury compounds are important. It has been found that an electrical discharge causes mercury vapor to combine with neon, argon, krypton, and xenon. These products, held together with van der Waals' forces, correspond to HgNe, HgAr, HgKr, and HgXe. Mercury is a virulent poison and is readily absorbed through the respiratory tract, the gastrointestinal tract, or through unbroken skin. It acts as a cumulative poison and dangerous levels are readily attained in air. Air saturated with mercury vapor at 20°C contains a concentration that exceeds the toxicity limits. The danger increases at higher temperatures. It is important therefore that mercury be handled with care. Containers of mercury should be securely covered and spillage should be avoided. If it is necessary to heat mercury or mercury compounds, it should be done in a well-ventilated hood. Methyl mercury is a dangerous pollutant and is now widely found in water and streams. The triple point of mercury, -38.8344C, is a fixed point on the International Temperature Scale (ITS-90).
The name derives from the Roman god Mercury, the nimble messenger of the gods, because the ancients used that name for the element known from prehistoric times. The symbol Hg derives from the Greek hydrargyrum for "liquid silver" or "quick silver".
Mercury was known to the ancient Chinese and Hindus and has been found in 3500 year old Egyptian tombs. Mercury is not usually found free in nature and is primarily obtained from the mineral cinnabar (HgS). Spain and Italy produce about half of the world's supply of Mercury.
From Greek hydoor. Known to ancient Chinese and Hindus; found in Egyptian tombs of 1500 B.C. Mercury is the only common metal liquid at ordinary temperatures. It only rarely occurs free in nature. The chief ore is cinnabar; Spain and Italy produce about 50% of the world's supply of the metal. The commercial unit for handling mercury is the "flask," which weighs 76 lb. The metal is obtained by heating cinnabar in a current of air and by condensing the vapor.
Pure mercury is a dense, mirror-bright liquid at room temperature, forming rounded droplets with high surface tension. It freezes to a soft, silvery solid below −38.83 °C and boils at 356.73 °C. Clean mercury wets few common surfaces but readily forms amalgams with many metals.
Mercury was historically important in thermometers, barometers, manometers, tilt switches, fluorescent lamps, dental amalgam, and laboratory electrodes. Some of these uses persist under restrictions or in specialized settings. Mercury vapor remains useful in certain discharge lamps, and mercury compounds have had roles as catalysts, reagents, and preservatives, though many have been replaced. Elemental mercury is still used in some artisanal and small-scale gold mining, a practice associated with substantial emissions.
Mercury can be used to make thermometers, barometers and other scientific instruments. Mercury conducts electricity and is used to make silent, position dependent switches. Mercury vapor is used in streetlights, fluorescent lamps and advertising signs.
Mercury easily forms alloys with other metals, such as gold, silver, zinc and cadmium. These alloys are called amalgams. Amalgams are used to help extract gold from its ores, create dental fillings (in the case of silver) and help extend the life of dry cell batteries (in the case of zinc and cadmium).
Mercury forms useful compounds with other elements. Mercuric chloride (HgCl2) is a very poisonous salt and was once used to disinfect wounds. Mercurous chloride (Hg2Cl2), also called calomel, is an antiseptic used to kill bacteria. Mercuric sulfide (HgS) is used to make a red paint pigment called vermilion. Mercuric oxide (HgO) is used to make mercury batteries.
Mercury is poisonous and can enter the body through the respiratory tract, the digestive tract or directly through the skin. It accumulates in the body, eventually causing severe illness or death.
The metal is widely used in laboratory work for making thermometers, barometers, diffusion pumps, and many other instruments. It is used in making mercury-vapor lamps and advertising signs, etc. and is used in mercury switches and other electronic apparatus. Other uses are in making pesticides, Mercury cells for caustic soda and chlorine production, dental preparations, anti-fouling paint, batteries, and catalysts.
Isotopes in Earth/Planetary Science
198Hg, 200Hg, and 202Hg are stable isotopes of mercury that can be used to study environmental sources and environmental sinks of this element in aquatic and terrestrial ecosystems. For example, in an ecosystem, different stable isotopes of mercury can be added to an upland region for run-off evaluation, to a lake for direct deposition analysis, and to a wetland region for outflow contribution analysis (Fig. IUPAC.80.1). As a result, it is possible to determine the entry points of mercury into an ecosystem and determine how the inputs of mercury affect the accumulation of this element in local fish populations. An international consortium of scientists is conducting an experiment called METAALICUS (Mercury Experiment To Assess Atmospheric Loading In Canada and the U.S.). This experiment includes determination of whether mercury contamination in fish is old or new mercury. Tracer studies were performed in northwestern Ontario at the Experimental Lakes Area of the Department of Fisheries and Oceans Canada [537] Toxic Substances Hydrology Program. Mercury-Contaminated Fish-Is it Old or New Mercury? U.S. Geological Survey (2014), Feb. 26; http://toxics.usgs.gov/highlights/mercury_contaminated_fish.html..
Isotopes Used as a Source of Radioactive Isotope(s)
202Hg is used to produce radioactive 203Hg (with a half-life of 46.6 days) via the 202Hg (n, γ) 203Hg reaction, which is used in gamma radiation calibration and medical tests.
Mercury chemistry is dominated by mercury(I) and mercury(II). Mercury(I) usually exists as the dimeric cation Hg₂²⁺, represented in mercury(I) chloride, Hg₂Cl₂. Mercury(II) chloride, HgCl₂, is more soluble and highly toxic. Mercury(II) sulfide, HgS, occurs as cinnabar and is very insoluble. Organomercury compounds such as methylmercury, CH₃Hg⁺, are environmentally important because they are readily bioaccumulated. Mercury forms amalgams with metals such as silver, gold, and tin.
See more information at the Mercury compound page.
Elemental mercury is hazardous mainly through inhalation of vapor, which is produced even at room temperature and can accumulate in poorly ventilated spaces. Soluble mercury(II) salts are corrosive and systemically toxic, while methylmercury, CH₃Hg⁺, is a potent neurotoxin that concentrates in food webs. Spills are treated as chemical contamination because droplets are persistent and difficult to remove. Heating mercury greatly increases vapor exposure.
Mercury is naturally released by volcanic activity, weathering, geothermal emissions, and ocean-atmosphere exchange, but human activities have greatly redistributed it. Coal combustion, metal smelting, waste burning, and gold mining are major anthropogenic sources. In aquatic sediments, microbes can convert inorganic mercury to methylmercury, CH₃Hg⁺, which biomagnifies in predatory fish and wildlife. Mercury can travel long distances in the atmosphere before deposition.
Mercury is produced mainly from cinnabar ore, HgS, and in some regions as a by-product of nonferrous metal processing or from recycling. Demand has fallen in many industrialized markets because of regulation and substitution in instruments, batteries, switches, and chlor-alkali technology. Supply is affected by restrictions on trade and storage as well as recovery from obsolete equipment. Significant consumption persists where alternatives are costly or poorly enforced, especially in small-scale gold extraction.
Virtually all mercury comes from cinnabar or mercury sulfide (HgS). Some sources of red cinnabar are so rich in mercury that droplets of elemental mercury can be found in random samples.
Mercury is a rare heavy element in cosmic terms. Its stable isotopes were formed chiefly by neutron-capture processes in earlier generations of stars, with later redistribution into the solar nebula. In the Solar System it is present in trace amounts in rocky bodies and meteorites, but it is volatile enough that planetary abundance depends strongly on condensation, heating, and loss processes.
- The chemical symbol Hg comes from hydrargyrum, meaning liquid silver.
- Mercury expands fairly uniformly with temperature, which made it valuable in older thermometers.
- Cinnabar, HgS, was used historically as the red pigment vermilion.
- Mercury droplets can divide into many beads, increasing surface area and vapor release.
- Aluminum structures can be damaged by mercury because amalgamation disrupts protective oxide behavior.
- Most dental amalgam is an alloy phase mixture rather than pure mercury.
