Non - metals
Non-metals are natural materials that do not produce heat or electricity and that are structurally brittle (can not be easily rolling, molding, extruding or pressing). Chemically, hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium are the non-metallic elements in the periodic table.
