Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. it’s a ductile metal with terribly high thermal and electrical physical phenomenon. Pure copper is soft and malleable; a freshly exposed surface incorporates a reddish-orange color. it’s used as a conductor of warmth and electricity, a building material, and a constituent of assorted metal alloys.

The metal and its alloys have been used for thousands of years. within the Roman era, copper was chiefly mined on Cyprus, therefore the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum. Its compounds square measure normally encountered as copper(II) salts, which regularly impart blue or green colors to minerals like azurite and turquoise and have been wide used traditionally as pigments. study structures built with copper corrode to provide green verdigris (or patina). decorative art conspicuously features copper, both by itself and as a part of pigments.

Copper is important to all living organisms as a trace dietary mineral as a result of it’s a key constituent of the respiratory protein advanced cytochrome enzyme. In molluscs and class copper is a constituent of the blood pigment hemocyanin, which is replaced by the iron-complexed hemoglobin in fish and different vertebrates. the most square measureas where copper is found in humans are liver, muscle and bone. Copper compounds square measure used as biological process substances, fungicides, and wood preservatives.
