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 the Cesium:Found in pollucite <(Cs4Al4Si9O26).H2O> and also as map in lepidolite. Human being production is about 20 lots per year. Main mining locations 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. Due to the fact that it ionizes readily, that is provided as an ion rocket engine propellant. Also used in photoelectric cells, atomic clocks, infared lamps.Additional Notes:Cesium have the right to have very serious results on the body if bring away in excess.
