History

History
The element Lithium was discovered by Johan August Arfwedson in year 1817 in Sweden. Lithium derived its name from the Greek word lithos, meaning 'stone'
The element Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Beryllium derived its name derived its name from from beryl, a mineral
