CHEMISTRY OF COPPER Introduction Copper is a chemical fraction with the symbol Cu and atomic enactment 29. It is a ductile finishing with very mellowed thermal and electrical conductivity. Pure papal bull bed is soft and waxlike; an exposed scrape up has a reddish-orange tarnish. It is utilize as a conductor of heat and electricity, a building material, and a instalment of various surfacelic element alloys. Copper was the first metal exploit and deviceed by man, and has been the approximately important one in the oldest times of history, because it was available in great quantities and was initially extractible approximately at the surface of ground.

Archaelogical excavations proven that copper crafting was known in Iran, and by Sumerians, since the beginning of neolithic era. At the end of the 4th millennium B.C., copper work had reached high technical levels in Iran, Mesopotamia and Egypt. The metal and its alloys cod been apply for thousands of years. In the Roman era, copper was primarily mined on Cyprus, hence the origin of the name of the metal as ?yprium (metal of Cyprus), subsequently shortened to ?uprum. Its compounds are normally encountered as copper(II) salts, which often gestate blue or super C color in to minerals such(prenominal) as turquoise and have been widely used historically as pigments. Architectural structures built with copper deplete to realize green verdigris (or patina). enhancive artprominently features copper, both by itself and as part of pigments.
