Who / wherein / when / How

Discoverer: Fausto and also Juan José de ElhuijarDiscovery Location: Vergara SpainDiscovery Year: 1783Name Origin:Swedish: tung sten (heavy stone): W symbol from its German surname wolfram i m sorry is called after wolframite.Abundance that Tungsten:Earth\"s Crust/p.p.m.: 160.6Seawater/p.p.m.: 0.000092Atmosphere/p.p.m.: 411Sun (Relative to H=1E12): 0.28Sources the Tungsten:Occurs in the mineral scheelite (CaWO4) and wolframite <(Fe,Mn)WO4>. Yearly world broad production is roughly 45,100 tons. Major mining locations are China, Malaysia, Burma, bolivia, canada, Australia, Japan and USA.Uses of Tungsten:Used widely in the electronics industry. Made into filaments for vacuum tubes and also electric lights. Also used in contact points in cars, welding electrodes, rocket nozzles and cutting tools. Linked with calcium or magnesium it renders phosphors.Additional Notes:Some sources offer the German chemist karl Wilhelm Scheele together the very first to isolation the steel in 1880, however most resources credit the Elhuijar brothers.
