The periodic table/Beryllium
Beryllium is the fourth element on the periodic table.
Discovery[edit | edit source]
Beryllium was discovered in France by Nicolas-Louis Vauquelin in 1798, and was isolated independently by Friedrich Wöhler and A.A. Bussy in 1828.
Beryllium in Gemstones[edit | edit source]
Beryllium is found in beryls (beryllium aluminum silicate, Be3Al2(SiO3)6), crysoberyls (BeAl2O4), emeralds, and aquamarines.

Uses[edit | edit source]
Beryllium is used in producing beryllium copper, in which beryllium copper is used to combine high strength with non magnetic and non sparking qualities ( screwdrivers, pliers, wrenches, cold chisels, knives, and hammers).
Due to Beryllium's oxide having a very high melting point, beryllium is used for nuclear work. Beryllium is used in nuclear weapon designs as the very outer layer of a pit (the explosive bomb, see the wikipedia article). The layers of beryllium added onto pits create more of a "push" for the implosion (process of collapsing or squeezing on themselves) of plutonium-239.
Beryllium is also used in jewelry (from gemstone), as Emerald and Aquamarine are two varieties of beryl.
