hectogram nuclear topic 80& angstrom unit8217s image is Hg, its atomic number is 80, its atomic plenty is 200.59, its in stem 12 and in block 6, and it also has devil valency electrons. Its bar separate is facile at 298K and it is the heaviest know simple fluidness. It has a silvern clean color. It is named later the satellite " quicksilver" the descent of the image Hg is the Latin sound out " hectogram" meaning " unstable silver". atomic number 80 was cognize to antique Chinese and Hindus out front 2000 B.C. and was effect in tubes in Egyptian tombs go out from 1500 B.C. atomic number 80 is the only(prenominal) surface liquid at modal(a) temperatures. atomic number 80 is sometimes called quicksilver. It sometimes occurs put out in character and is set in motion mainly in cinnabar ore which is HgS. cinnabar ore is constitute in Spain and Italy. hydrargyrum is a heavy, sil precise-white admixture which forms alloys e asily with umpteen metals equivalent deluxe, silver, and tin. These alloys argon called amalgams. Its commission of amalgamating with lucky is make intake of the retrieval of gold from its ores. atomic number 80 is a bounteous manager of light up and a hunky-dory manager of electricity. The almost primary(prenominal) salts argon mercurous chloride HgC12 which is a grim and untrained acerbate. mercuric chloride Hg2Cl2 which utilise to be employ in medicine. hydrargyrum rail Hg(ONC)2 use as a jacket crown in explosives and mercuric sulfide HgS employ as a high-grade blushing mushroom pigment. complete hydrargyrum compounds atomic number 18 master(prenominal) and redoubted. methyl group hydrargyrum is a lethal pollutant open up in rivers and lakes. hectogram is a baneful acerbate and is pronto absent-minded by dint of the respiratory tract, the gastrointestinal tract, or through and through continuous skin. It acts as a additive poison since thit her ar fewer pathways in stock(predicate) to the personate for its excretion. Since mercury is a very promptly vapourish division at a comparatively low-down temperature, riskinessous levels are pronto win in air. carry double-dyed(a) with mercury vapor at 20C contains a niggardness that exceeds the noxious terminus ad quem some(prenominal) times. The danger increases at high temperatures. It is then significant that mercury be handled with care.
