Arsenic (As)
Arsenic ([Ar]3d104s24p3) (CAS 7440-38-2) a steel-gray, semi-metallic solid, is very brittle, crystalline, and poisonous. Elemental arsenic occurs in two solid modifications: the ordinary, stable, metallic-gray form and the yellow form. It oxidizes in air and, when heated, is rapidly oxidized to arsenous oxide (AS2O3) with a garlic odor. Arsenic is used as a doping agent in semiconductor materials.

Arsenic (As) is a naturally occurring element found in the earth's crust. Arsenic combines with oxygen, chlorine, and sulfur to form inorganic arsenic compounds, which are highly toxic. In animals and plants, arsenic combines with carbon and hydrogen to form organic arsenic compounds, which are not...
