What are metals and non-metals?

  • Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.
  • The metals of antiquity are the seven metals that humans had identified and found use for in prehistoric times: gold, silver, copper, tin, lead, iron, and mercury.
  • Aluminum, cadmium, chromium, copper, iron, lead, nickel, tin, zinc, or any combination of these elements are considered common metals.
  • Non-metals are natural materials that do not produce heat or electricity and that are structurally brittle (can not be easily rolled, molded, extruding, or pressed). Hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium are the non-metallic elements in the periodic table.
