Lithium Expert on Element
Lithium ・Lithium [lithｴEum] a metallic chemical element. ... 392eV ・Critical Point: 3223K ・Oxidation Number +1 ・Classification: Alkali Metal ・Block: S- block ・Structure: Crystal ・Isotopes: Li-6 and Li-7 ・Number of valence electrons: 1 ・Phase of Matter at Room Temperature: Solid The name lithium comes from the Greek word lithos which means stone because lithium was first discovered in rocks and the other two alkali metals were first discovered in plants. Lithium was first found in the mineral called petalite (LiAl(Si2O5)2, lithium aluminium silicate). A relatively common element, lithium accounts for about 0. ... Lithium is widely distributed in nature; it is found in the soil, in plants, in animals, and in the human body. ... Although at least 145 minerals contain lithium, only a few, including spodumene (the largest commercial source) and petalite, are important sources The mineral petalite (which contains lithium ) was discovered by the Brazilian scientist Jos・Bonif當io de Andrada e Silva towards the end of the 18th century while visiting Sweden. Lithium itself was discovered by Johan August Arfvedson in 1817 during an analysis of petalite ore, which was taken from the Swedish island of Ut・ Arfvedson later discovered lithium in the minerals spodumene and lepidolite.
