Discoverer: recognized to old civilizationDiscovery Location: UnknownDiscovery Year: UnknownName Origin:Latin: cyprium (island the Cyprus well known for its copper mines).Abundance of 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 that Copper:Pure copper occurs rarely in nature. Normally copper found in together minerals as azurite, malachite and also bornite and in sulfides together in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides prefer cuprite (Cu2O). Copper is derived by smelting, leaching and by electrolysis. Yearly world manufacturing is roughly 6,540,000 tons. Main mining locations are in USA, Zaire, Zambia, Canada, Chile, Cyprus, Russia and also Australia.Uses the Copper:Most frequently used as an electric conductor. That is alloys are offered in jewelry, bronze sculptures and also for coins. The skin the the Statue the Liberty is made of copper.Additional Notes:Copper is a an extremely interesting element. It is just one of the transition elements the actually supplies electrons from one of the inside orbitals in chemical reactions. In addition, the has more than one oxidation state. Like countless of the shift elements, copper has a colored ion. Copper commonly 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 among the earliest recognized metals, having reportedly been mined because that over 5000 years. In nature it has two isotopes, 63 (69.09%), which has actually 29 electrons and also protons and also 34 neutrons, and also 65 (30.91%), which has actually 29 electrons and protons and 36 neutrons. Brass and bronze are alloys the copper.
