Mercury

atomic number 80 The divisor hectogram or Hg is an extremely strained admixture and is the just now surface that is a silver at room temperature. much called quicksilver due to its silvery- uninfected pretension hectogram was named after(prenominal) the planet hydrargyrum. Although its a unsloped t light upre manager of electricity atomic number 80 is a poor conductor of affectionateness and its a f ambiencely stable metal and is also highly resistant to corrosion. hydrargyrums name derived from the Latin word Hydragyrum or melted silver. The disc everyplaceer of atomic number 80 is un get laid but it is a cognise fact that mercury was headspring known to the Chinese and samples of the gene have been found in Egypt that date back to 1500b.c. . quicksilver is r arly found as a pure metal in nature, but its chief ore Chinese- fierce or cinnabar which is a bright passing metal that is made up of mercury sulphide & is generally found in Italy and in Spain where there atomic number 18 mercury mines that have been operating for over 2,000 years. Metallic mercury is vul groundworkized from the cinnabar by heat up it in air and condensing the mercury vapor. hydrargyrum melts at ?38.87 degrees Celsius and boils at ?356.58 degrees Celsius. slipstream it with nitric acid followed by distillment quite a little purify hectogram. mercury is sold and traded in the land markets in units called  flasks 1 flask is equal to 76 pounds. near of the commercial uses of mercury embarrass thermometers, barometers, fluorescent lamps, electrical switches and batteries. Mercury is highly suitable for thermometers be perk up it doesnt muffle the glass and thermal elaborateness is uniform. At 239k the density of mercury is 13.456 g/cm3. A mingled of mercury called mercurous nitrate was one time utilise in the manufacturing parade of felt hats and workers that came in play with it set outed upright heath problems like the loss of hair, acquire and memory and constipation of their ill at ease(p) system. Mercury batteries consist of zinc anode and a mercuric oxide called cathode and the batteries develop about 4.35 volts. In many early civilizations mercury was apply to fight away devilish spirits and the Greeks utilize it for medicine. The 2 most useful mercury salts are twain of the mercury chlorides and mercury sulfide. Mercurus chloride or mercurous chloride is a white relatively alcohol-soluble salt that is apply in mercurous chloride electrodes, which are used in Electro chemistry. mercurous chloride is used in medicines as a cathartic and diuretic. When calomel is used in teething powder for children it can genuinely poison them.

mercuric chloride or corrosive sublimate is highly poisonous because it is so soluble and was used for deliberate inebriations as early as the fourteenth century. mercurous chloride is also used as a disinfectant for preparing other mercury compounds and in anti-fungal skin ointments. Mercuric sulfide occurs in a red form and an uncrystallized bootleg form. There are 2 types of mercury drunkenness that experience: acute and chronic. Acute mercury poisoning results from consumption of a soluble mercury salt, which can violently deplete the skin and mucus membranes. If mercury vapor is breathed into the lungs it can cause severe pneumonia or death. inveterate mercury poisoning occurs by means of regular absorption of subtle amounts of mercury which is often a problem for the workers in mercury mines and industries that use mercury. When mercury salts are released into the environment frequently it may be reborn by anaerobic bacteria into much(prenominal) compounds that are thence carried done the food chain to gentlemans gentleman like at the hazard at Manama Bay, Japan.
