Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green.
3) Copper is resistant to corrosion (it is very unreactive). Uses. 1) Copper is the main metal for electrical wiring (compare with aluminium). 2) Copper is malleable which makes it an ideal material for gas pipes and water pipes.Copper is below hydrogen in the reactivity series and therefore it does not react with water. Copper is the metal used for plumbing in houses.ses. 1) Copper is the main metal for electrical wiring (compare with aluminium). 2) Copper is malleable which makes it an ideal material for gas pipes and water pipes.
