bromine g. boron h.silver Arsenic is a poisonous metalloid that is found in two main allotropic forms: a metallic gray form, and a nonmetallic yellow form. The name of the element is derived from the Greek word arsenikon , the name for the arsenic-containing mineral orpiment. The first element in the group is the nonmetal nitrogen (N), followed by phosphorus (P), another nonmetal. Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal .
