ArsenicArsenic is a chemical element that has the symbol As and atomic number 33. Arsenic was discovered by Albertus Magnus in 1250. Its Atomic Mass is 74.92. Its Ionic Charge is Its position in the periodic table is shown at right. This is a notoriously poisonous metalloid that has many allotropic forms: yellow and several black and gray forms are a few that are seen. Three metalloidal forms of arsenic with different crystal structures are found free in nature , but it is more commonly found as arsenide and arsenate compounds. Several hundred such mineral species are known. Arsenic and its compounds are used as pesticides, herbicides, insecticides and various alloys. The most common oxidation states for arsenic are -3 , +3 or arsenites, and most organoarsenic compounds), and +5 : the most stable inorganic arsenic oxycompounds). Arsenic also bonds readily to itself, forming, for instance, As-As pairs in the red sulfide realgar and square As43- ions in the arsenide skutterudite. In the +3 oxidation state, the stereochemistry of arsenic is affected by possession of a lone pair of electrons. (From the Wikpedia article Arsenic.) Download PDF containing detailed information.
