Metals and nonmetals are materials that show different properties. Metals are malleable, ductile, sonorous, hard, lustrous, and good conductors of heat and electricity. Nonmetal is not malleable, not hard, nonductile, non-lustrous, and a bad conductor of heat and electricity. Some of them show some exceptions which make them unique.
