Who / where / when / How

Discoverer: Nicholas luigi VauquelinDiscovery Location: Paris FranceDiscovery Year: 1797Name Origin: indigenous the mineral beryl.Abundance the Beryllium:Earth"s Crust/p.p.m.: 2.6Seawater/p.p.m.: Atlantic Suface: 8.8E-08Atlantic Deep: 1.75E-07Pacific Surface: 3.5E-08Pacific Deep: 2.2E-07Atmosphere/p.p.m.: N/ASun (Relative to H=1E12): 14Sources that Beryllium:Found mainly in minerals choose beryl and chrysoberyl (Al2BeO4). Total human being production every year is approximately 364 tons. Main mining locations are Brazil,USA, Madagascar, Germany, Czech Republic, Russia and also India. Total world reserves estimated to be approximately 400,000 tons.Uses that Beryllium:Its ability to absorb large amounts of heat makes it advantageous in spacecraft, missiles, aircraft, etc. Emeralds space beryl crystals with chromium traces giving them their green color. Additionally used in irradiate weight metal alloys, X-ray tube windows, watch springs and sparkless tools.Additional Notes:Beryllium was an initial discovered by Vauquelin in 1797, however, it was not issolated till 1828 in Berlin Germany and A.A.B bussy in Paris France. Beryllium comes from Greek beryllos, beryl. That has also been dubbed Glucinium or Glucinum from the Greek word glykys which method "sweet." Beryllum is discovered in beryl, chrysoberyl and also phenacite. Aquamarine and also emeralds are precious develops of beryl (3BeO.Al2O3.6SiO2). It has actually a high melting point for a irradiate metal and also is much more elastic 보다 steel. The is provided in computer parts, gyroscopes and also for construction. Beryllium and its salts space toxic and also should be taken on with great care. Perform not taste that to confirm that that is sweet. Beryllium is a potential work carcinogen (lung cancer).
