The story of the word
Johan August Arfwedson found the new alkali in the mineral petalite in 1817, and Berzelius named it from λίθος, stone. The point of the name was a contrast: soda and potash had come from plant ash, while this alkali came out of rock. Its use as a mood stabiliser was rediscovered by John Cade in Australia in 1949, which makes it one of the few elements prescribed as a drug in its raw ionic form.
