Planetary Bohr Model of Copper (Cu)
Description
Malleable, ductile, reddish-brown metal.
Uses
Most often used as an electrical conductor. Also used in the manufacture of water pipes. Its alloys are used in jewelry and for coins.
Sources
Pure copper occurs rarely in nature. Usually found in sulfides as in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides like cuprite (Cu2O).
Pronounciation (English)
KOP-er
