Its Neither a metal or a non metal. Its a compound formed from copper, nitrogen and oxygen. Its also called an ore from which copper can be extracted in its original metal form up to 99% purity. This substance is actually a salt that can be formed in many ways. One of these ways is mixing Copper and Nitric Acid, another is Copper Carbonate and Nitric Acid. This salt is also a compound (a substance made of more than one types of atom, which are chemically joined together).
