Beryllium

Symbol and Description Symbol: Be Description: is the lightest member of the alkaline earth metals family. Its atomic number is 4 and the avg. atomic mass is 9.01218. It is a silvery metal.

WHY IT’S CALLED BERYLLIUM It’s named after beryllos, the Greek name for the mineral beryl, the element was originally known as glucinium — from Greek glykys, meaning "sweet" — to reflect its characteristic taste.

HOW, WHERE, WHO? HOW: Discovered in the oxide form by Vauquelin in both beryl and emeralds in 1798. WHERE: In France. WHO: By the French chemist Louis Nicolas Vauquelin.

USED FOR? Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. ... Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites. Beryllium is also used as a moderator in nuclear reactors.

OBTAINED? Today, beryllium is primarily obtained from the minerals beryl (Be3Al2(SiO3)6) and bertrandite (4BeO. 2SiO. H2O) through a chemical process or through the electrolysis of a mixture of molten beryllium chloride (BeCl2) and sodium chloride (NaCl).
