Although the early Chinese, Greek mined arsenic compounds and Egyptian civilizations, it is believed that Albertus Magnus, a German alchemist, first identified arsenic itself.

The element is a steel Grey, actually brittle, crystalline, semimetallic (metalloid) solid. It tarnishes in air, and when heated rapidly oxidizes to arsenous oxide which has a garlic odour. Arsenic and its compounds be poisonous. Upon estrus arsenic and some minerals containing arsenic, it sublimes (transfers from the solid to the vapourific state, without passing through with(predicate) the liquid state).

Chemical properties Synonyms for arsenic argon arsenic-75, metallic arsenic, arsenic black, arsenicals, and colloidal arsenic. The ino rganic arsenic compounds ar solids at norma! l temperatures and are not likely to volatilize. In water, they range from quite meltable (sodium arsenite and arsenic acid) too much insoluble (arsenic trisulfide). Some organic arsenic compounds are gases or low-boiling liquids at normal temperatures. Poisonous gas is produced by arsenic in a fire. Arsenic roughly acid or acid mist can clitoris a very(prenominal) deadly gas, arsine. Twenty-one arsenic compounds... If you urgency to get a full essay, order it on our website: OrderEssay.net
