Lithium


Lithium was discovered in 1817 by Arfwedson when studying a mineral called petalite. However, he did not isolate the metal. The metal was fist isolated in 1855 by Bunsen and Matthiessen in 1855, through the electrolysis of molten lithium chloride. Its name derives from the Greek word for stone, since it was believed that lithium was only present in the stones.
