· Metals, generally have a lustrous appearance, are typically malleable, ductile and conducts electricity and heat relatively well. Copper, which occurs in its native form, is the first metal discovered given its distinctive appearance, heaviness, and malleability compared to other stones or pebbles. Almost all the metals are of a great use to human beings as [.]
