Discoverer: Gustov R. Kirchoff, Robert BunsenDiscovery Location: Heidelberg GermanyDiscovery Year: 1860Name Origin: Latin: caesius (sky blue); that is salts revolve flames blue.Abundance of Cesium:Earth"s Crust/p.p.m.: 3Seawater/p.p.m.: 0.0003Atmosphere/p.p.m.: N/ASun (Relative come H=1E12): 80Sources of Cesium:Found in pollucite <(Cs4Al4Si9O26).H2O> and as map in lepidolite. World production is approximately 20 loads per year. Primary mining areas are in Bernic Lake (Manitoba, Canada), Bikita (Zimbabwe) and also South-West Africa.Uses the Cesium:Used as a "getter" to remove air traces in vacuum tubes. Because it ionizes readily, the is provided as one ion rocket engine propellant. Additionally used in photoelectric cells, atomic clocks, infared lamps.Additional Notes:Cesium can have an extremely serious effects on the body if taken in excess.
