Chemical properties

Copper is not very reactive. It does react with air, but it does so very slowly.

Compounds

What color are copper sulfate and copper carbonate?

Uses

Copper is used in wire, jewelry, coins, cooking pots, and pipes. It is also used in the manufacture of a wide range of alloys (including brass and bronze) and as a coating on objects to improve their appearance and prevent them from corroding.

Notes

The Statue of Liberty

The Statue of Liberty is made from copper. The green color, or patina, of the statue is the result of copper compounds that form on its surface.
