Mercury(II) chloride or mercuric chloride (historically "corrosive sublimate") is the chemical compound of mercury and chlorine with the formula HgCl 2.It is white crystalline solid and is a laboratory reagent and a molecular compound that is very toxic to humans.

The element's atomic mass is 200.59 grams per mole and its specific gravity is 13.5 times that of water. Acidic surface waters can contain significant amounts of mercury. Mercury is a chemical element with the symbol Hg and atomic number 80. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. Although its form and availability to living organisms may change over time, mercury persists in the environment. Once mercury has reached surface waters or soils microrganisms can convert it to methyl mercury, a substance that can be absorbed quickly by most organisms and is known to cause nerve damage. Chromosomal damage is known to cause mongolism. The metal is a fair conductor of electricity, but a poor conductor of heat. Mercury is moderately active. Vapours are purged into a cold vapour cell on the atomic absorption spectrophotometer and quantified using a wavelength of 257.3 nm. Chemical properties of Mercury 80 Hg Mercury 200.59 Period: 6 Melting Point: -39 Boling Point: 357 Ionization Energy: 10,4375 Electrone Gativity: 2,28 Covalenz Radius: 144 Discovery Year: ancient Inventor: Ramsay, Sir William & Strutt, John The abundance of mercury in the Earth's crust is estimated to be about 0.5 parts per million. Since mercury can be adsorbed easily onto small particles of matter, some scientists use the notation Hg(p) to represent elemental mercury attached onto or absorbed into a particle. Mercury, Silver Liquid Mercury, Red Mercury, Metallic Mercury CAS NO.7439-97-6: 7439-97-6: Hebei yanxi chemical co.,LTD. J. Chem. The total electrical charge of the nucleus is therefore +Ze, where e (elementary ch… These alloys are called amalgams. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. Some forms of human activity release mercury directly into soil or water, for instance the application of agricultural fertilizers and industrial wastewater disposal. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Classified as a transition metal, Mercury is a liquid at room temperature. Anonymous. This can cause harmful effects, such as nerve, brain and kidney damage, lung irritation, eye irritation, skin rashes, vomiting and diarrhoea. Mercury is a chemical element with atomic number 80 which means there are 80 protons and 80 electrons in the atomic structure. Fortunately, mercury does not form amalgam with iron, which allows for the element to be shipped in standard iron flasks containing 76 pounds, or 34.5 kilograms, of liquid mercury. Cattle breeding products can also contain eminent quantities of mercury. The Physical and Chemical Properties are the characteristics of a substance, like Mercury, which distinguishes it from any other substance. It is commonly known as quicksilver and was formerly named hydrargyrum. Mercury is the only common metal which is liquid at ordinary temperatures. The same amount has existed on the planet since the earth was f… Mercury reacts with chlorine and sulfur, to form compounds such as mercuric chloride, mercurous chloride, mercuric sulfide, etc. Mercuric sulphate is used as a catalyst in organic chemistry.
