History

History
The element Osmium was discovered by Smithson Tennant in year 1803 in United Kingdom. Osmium derived its name from from the Greek osmè, meaning 'smell'
The element Thorium was discovered by Jöns Jakob Berzelius in year 1829 in Sweden. Thorium derived its name derived its name from from Thor, the Scandinavian god of thunder
