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 Rubidium was discovered by Robert Bunsen in year 1861 in Germany. Rubidium derived its name derived its name from from the Latin rubidus, meaning 'deep red'
