Although its form and availability to living organisms may change over time, mercury persists in the environment. That makes it one of the 20 least common elements. As a chemical element, mercury cannot be created or destroyed. Refer to the article on Mercury Element for additional information and facts about this substance. 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. Much less mercury is now used in consumer batteries and fluorescent lighting, but it has not been entirely eliminated. The Physical and Chemical Properties are the characteristics of a substance, like Mercury, which distinguishes it from any other substance. You will not receive a reply. All forms of mercury are quite toxic, and each form exhibits different health effects. The same amount has existed on the planet since the earth was f… 1946-47]. When the pH values are between five and seven, the mercury concentrations in the water will increase due to mobilisation of mercury in the ground. J. Chem. Mineable reserves are around 600.000 tonnes. Mercury fulminate, Hg(CNO)2, is used as a detonator. Mercury is also found in two positively charged, or cationic, states, Hg2+ (mercuric) and Hg1+(mercurous). Bromine is a non-metal. Mercuric oxide is used in skin ointments. The element's atomic mass is 200.59 grams per mole and its specific gravity is 13.5 times that of water. Mercury is a silvery-white, shiny metal, which is liquid at room temperature. Still mercury concentrations in the environment are increasing; this is ascribed to human activity. Metallic mercury is a shiny, silver-white, odorless liquid. Its Its ease in amalgamating with gold is used in the recovery of gold from its ores. Never give anything by mouth to an unconscious person. Fish are organisms that absorb great amounts of methyl mercury from surface waters every day. It has no RADIOACTIVITY but heavy to disintegrate hence harmful. Elemental mercury is liberated by hydrochloric acid and stannous chloride. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. The structure, chemical formula, and physical and chemical properties of some Hg-containing compounds are shown in Table 2-1.
