It is not known who discovered mercury, but it has been found in Egyptian tombs dating back over 3, years. How old is Mercury the element? Named after the fastest-moving planet in the solar system, mercury has been known to humanity for ages. In fact, evidence of its use has been found in China, India and Egypt, and traces of mercury were found in 3,year-old Egyptian datingesk.comy is a very toxic element.. What is the element mercury named after?

Previous Element Gold. Next Element Thallium. What's in a name? Named after the planet Mercury. Mercury's chemical symbol comes from the Greek word hydrargyrumwhich means "liquid silver. Say what? Mercury is pronounced as MER-kyoo-ree. Mercury was known to the ancient Chinese and Hindus and how to make fake rock walls for reptiles been found in 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. 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 goldsilverzinc 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 HgCl 2 is a very poisonous salt and was once used to disinfect wounds. Mercurous chloride Hg 2 Cl 2also 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. How to use forms in wordpress Crustal Abundance : 8. Number of Stable Isotopes : 7 View all isotope data.

The Element Mercury

There is evidence that mercury was discovered in B.C., but other sources say that mercury has been found in year-old Egyptian tombs. Mercury was known in Egypt and also probably in the East as early as bce. The name mercury originated in 6th-century alchemy, in which the symbol of the planet was used to represent the metal; the chemical symbol Hg derives from the Latin hydrargyrum, “liquid silver.”. Although its toxicity was recognized at an early date, its main application was for medical purposes. Discovered in gadolinite, but Mosander showed later that its ore, yttria, contained more elements. [60] [61] Wohler mistakenly thought he had isolated the metal in from a volatile chloride he supposed to be yttrium chloride, [62] [63] but Rose proved otherwise in .

Mercury Hg , also called quicksilver , chemical element , liquid metal of Group 12 IIb, or zinc group of the periodic table. Mercury was known in Egypt and also probably in the East as early as bce. Mercury is the only elemental metal that is liquid at room temperature.

Cesium melts at about It boils at It alloys with copper , tin, and zinc to form amalgams, or liquid alloys. An amalgam with silver is used as a filling in dentistry.

Mercury does not wet glass or cling to it, and this property, coupled with its rapid and uniform volume expansion throughout its liquid range, makes it useful in thermometers. Barometers and manometers utilize its high density and low vapour pressure. Gold and silver dissolve readily in mercury, and in the past this property was used in the extraction of these metals from their ores. The good electrical conductivity of mercury makes it exceptionally useful in sealed electrical switches and relays.

An electrical discharge through mercury vapour contained in a fused silica tube or bulb produces a bluish glow rich in ultraviolet light , a phenomenon exploited in ultraviolet, fluorescent, and high-pressure mercury-vapour lamps. Much mercury is utilized in the preparation of pharmaceuticals and agricultural and industrial fungicides.

The use of mercury in the manufacture of chlorine and caustic soda sodium hydroxide by electrolysis of brine depends upon the fact that mercury employed as the negative pole, or cathode , dissolves the sodium liberated to form a liquid amalgam.

An interesting application, though not of great commercial significance, is the use of mercury vapour instead of steam in some electrical generating plants, the higher boiling point of mercury providing greater efficiency in the heat cycle. The principal ore is the red sulfide, cinnabar. Native mercury occurs in isolated drops and occasionally in larger fluid masses, usually with cinnabar, near volcanoes or hot springs.

Over two-thirds of the world supply of mercury comes from China , with most of the remainder coming from Kyrgyzstan and Chile; it is often a by-product of gold mining. Cinnabar is mined in shaft or open-pit operations and refined by flotation.

Most of the methods of extraction of mercury rely on the volatility of the metal and the fact that cinnabar is readily decomposed by air or by lime to yield the free metal.

Because of the toxicity of mercury and the threat of rigid pollution control , attention is being directed toward safer methods of extracting mercury. These generally rely on the fact that cinnabar is readily soluble in solutions of sodium hypochlorite or sulfide, from which the mercury can be recovered by precipitation with zinc or aluminum or by electrolysis. For treatment of the commercial production of mercury, see mercury processing ; for mineralogical properties, see native element [table].

Extremely rare natural alloys of mercury have also been found: moschellandsbergite with silver , potarite with palladium , and gold amalgam. Mercury is extracted from cinnabar by roasting it in air, followed by condensation of the mercury vapour. Mercury is toxic. Poisoning may result from inhalation of the vapour, ingestion of soluble compounds , or absorption of mercury through the skin.

Natural mercury is a mixture of seven stable isotopes: Hg 0. As a wavelength standard and for other precise work, isotopically pure mercury consisting of only mercury is prepared by neutron bombardment of natural gold, gold Mercury Article Media Additional Info.
