WebAug 15, 2024 · Arsenic is a highly poisonous metalloid. Because it is a metalloid, arsenic has a high density, moderate thermal conductivity, and a limited ability to conduct electricity. The oxidation states of arsenic are +5, +3, +2, +1, and -3. The three allotropic forms of arsenic are yellow, black, and gray; the gray allotrope is the most common. WebJan 1, 2005 · Arsenic compounds have been widely used as drugs in the past and were used until recently as growth promoters for some farm animals.
