Discoverer: recognized to old civilizationDiscovery Location: UnknownDiscovery Year: UnknownName Origin:Latin: cyprium (island of Cyprus renowned 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 come H=1E12): 1.15Sources the Copper:Pure copper occurs seldom in nature. Normally copper discovered in together minerals as azurite, malachite and also bornite and in sulfides as in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides favor cuprite (Cu2O). Copper is obtained by smelting, leaching and by electrolysis. Annual world production is approximately 6,540,000 tons. Main mining areas are in USA, Zaire, Zambia, Canada, Chile, Cyprus, Russia and also Australia.Uses that Copper:Most frequently used together an electrical conductor. Its alloys are offered in jewelry, copper sculptures and also for coins. The skin the the Statue the Liberty is do of copper.Additional Notes:Copper is a very interesting element. It is just one of the shift elements the actually offers electrons from one of the inside orbitals in chemistry reactions. In addition, that has more than one oxidation state. Like countless of the transition elements, copper has a fancy ion. Copper frequently forms a bluish green solution. Copper (Cu) has actually two valences Cu i (cuprous) has actually one valence electron and Cu II (cupric) has two valence electrons. Copper was among the earliest well-known metals, having actually reportedly to be mined for over 5000 years. In nature it has two isotopes, 63 (69.09%), which has actually 29 electrons and protons and 34 neutrons, and also 65 (30.91%), which has actually 29 electrons and also protons and 36 neutrons. Brass and also bronze space alloys of copper.
