Background:
  • The discovery of Lithium
    • Discovered by a scientists named Johan August Arfwedson in 1817.
    • The element was first isolated by a scientists named, William Thomas Brande in 1812.
    • The origin of the name, Lithium, comes from a Greek word which is "stone". Lithium was discovered from a mineral, while other common alkali metals were discovered from plant material. This is thought to explain the origin of the element's name; from 'lithos' (Greek for 'stone').
  • Common uses
    • The most common use of Lithium is ceramics and glass.
    • Also used in electrical and electronics.
