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 Mendelevium was discovered by Lawrence Berkeley National Laboratory in year 1955 in United States. Mendelevium derived its name derived its name from from Dmitri Mendeleev, chemist and inventor
