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

Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).
