Discoverer: well-known to ancient civilizationDiscovery Location: UnknownDiscovery Year: UnknownName Origin:Latin: cyprium (island of Cyprus famous for that is copper mines).Abundance the Copper:Earth"s Crust/p.p.m.: 50Seawater/p.p.m.: Atlantic Suface: 0.00008Atlantic Deep: 0.00012Pacific Surface: 0.00008Pacific Deep: 0.00028Atmosphere/p.p.m.: N/ASun (Relative to H=1E12): 1.15Sources the Copper:Pure copper occurs seldom in nature. Usually copper found in such minerals as azurite, malachite and bornite and also in sulfides as in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides choose cuprite (Cu2O). Copper is derived by smelting, leaching and also by electrolysis. Yearly world production is roughly 6,540,000 tons. Main mining areas are in USA, Zaire, Zambia, Canada, Chile, Cyprus, Russia and Australia.Uses that Copper:Most regularly used together an electric conductor. That is alloys are provided in jewelry, bronze sculptures and for coins. The skin of the Statue that Liberty is make of copper.Additional Notes:Copper is a an extremely interesting element. It is among the shift elements that actually supplies electrons from among the inner orbitals in chemistry reactions. In addition, it has an ext than one oxidation state. Like countless of the change elements, copper has actually a colored ion. Copper commonly forms a bluish green solution. Copper (Cu) has actually two valences Cu i (cuprous) has actually one valence electron and also Cu II (cupric) has actually two valence electrons. Copper was among the earliest recognized metals, having actually reportedly to be mined for over 5000 years. In nature it has actually two isotopes, 63 (69.09%), which has 29 electrons and protons and also 34 neutrons, and 65 (30.91%), which has 29 electrons and also protons and also 36 neutrons. Brass and bronze space alloys the copper.
