Properties

Copper is a fairly soft, reddish brown metal that is quite ductile. It is one of the best conductors of heat and electricity of all elements. Its melting point is 1,982°F (1,083°C), its boiling point is 4,703°F (2,595°C), and its density is 8.96 grams per cubic centimeter.

Copper is a moderately reactive metal that dissolves in most acids and alkalis. One of its most interesting properties is its tendency to react in moist air with water and carbon dioxide to form hydrated copper carbonate [Cu2(OH)2CO3]. Hydrated copper carbonate has a beautiful greenish color that accounts for the patina that develops over time on buildings and other structures coated with copper...
