Copper Copper is a metal that occurs naturally in rock and soil. Copper's distinctive red color makes it easy to identify.Copper (Cu) is one of the best electrical conductors of all the metals, and its abundance helped it become the material that tied the world together in telecommunications .
Copper was one of the earliest elements known to man. CITATION REQUIREDThe discovery of copper dates from prehistoric times.It has been reported that copper was discovered in 9000 BC found in Iraq.Methods for refining copper from its ores were discovered around 5000BC and a 1000 or so years later it was being used in pottery in North Africa.
Copper has two stable isotopes,63Cu and 65Cu. CITATION REQUIREDCopper also has 27 radioisotopes.Unstable copper isotopes with atomic masses below 63 tend to undergo β+ decay, while isotopes with atomic masses above 65 tend to undergo β− decay. 64Cu decays by both β+ and β−.
