History
Name | Bromine | Lithium |
History | The element Bromine was discovered by J. Balard and C. Löwig in year 1825 in France. Bromine derived its name from the Greek bromos, meaning 'stench'. | The element Lithium was discovered by A. Arfwedson in year 1817 in Sweden. Lithium derived its name the Greek word lithos, meaning 'stone'. |
