Discoverer: known to old civilizationDiscovery Location: UnknownDiscovery Year: UnknownName Origin:Latin: cyprium (island of Cyprus renowned for the copper mines).Abundance that 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 of Copper:Pure copper occurs hardly ever in nature. Usually copper found in together minerals together azurite, malachite and also bornite and in sulfides together in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides favor cuprite (Cu2O). Copper is derived by smelting, leaching and by electrolysis. Annual world production is about 6,540,000 tons. Main mining areas are in USA, Zaire, Zambia, Canada, Chile, Cyprus, Russia and also Australia.Uses that Copper:Most often used as an electric conductor. Its alloys are offered in jewelry, copper sculptures and for coins. The skin of the Statue of Liberty is do of copper.Additional Notes:Copper is a very interesting element. It is just one of the shift elements that actually provides electrons from one of the inner orbitals in chemistry reactions. In addition, it has an ext than one oxidation state. Like countless of the change elements, copper has a fancy ion. Copper frequently forms a bluish green solution. Copper (Cu) has two valences Cu i (cuprous) has one valence electron and also Cu II (cupric) has actually two valence electrons. Copper was one of the earliest known metals, having actually reportedly to be mined because that over 5000 years. In nature it has two isotopes, 63 (69.09%), which has 29 electrons and protons and also 34 neutrons, and 65 (30.91%), which has actually 29 electrons and protons and 36 neutrons. Brass and also bronze are alloys that copper.
