copper

     

Copper (pronounce /ˈkɒpɚ/) is a chemical element with the symbol Cu (Latin: cuprum) and atomic number 29. It is a ductile metal with excellent electrical conductivity and is rather soft in its pure state and has a pinkish luster which is (beside gold) unusual for metals which are normally silvery white. It finds extensive use as an electrical conductor, heat conductor, as a building material, and as a component of various alloys.
