Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29.
It is a ductile, semi-precious metal with very high thermal and electrical conductivity.
Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish.
It is used as a conductor of heat and electricity, a building material, and a constituent
of various metal alloys. Copper can be found as either native copper or as part of minerals.
