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 Osmium was discovered by Smithson Tennant in year 1803 in United Kingdom. Osmium derived its name derived its name from from the Greek osmè, meaning 'smell'
