2H2O + 2Li -> 2LiOH +H2
Lithium was named by J.J. Berzelius in 1818 from the Greek word lithos. It was discovered by the Swedish chemist Johan August Arfwedson (1792?â????1841), a student of Berzelius, in the previous year, when he analysed the mineral petalite (LiAlSi4O10).
It has the second widest range of application of the alkali metals (sodium has the most).
