Which list of elements consist of a metal, a metalloid and a nonmetal?(1) Li, Na, Rb (2) Cr, Mo, W (3) Sn, Si, C (4) O, S, Te 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. In Groups 4A-6A, there are several elements whose symbols begin with S.
