Copper (Cu) Metals 

Copper is a reddish metal with a face-centered cubic crystalline structure. Copper is malleable, ductile, and an extremely good conductor of both heat and electricity. It is softer than iron but harder than zinc and can be polished to a bright finish. It is element belong to group IB. Copper has low chemical reactivity. In moist air it slowly forms a greenish surface film called patina; this coating protects the metal from further attack.
