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 Plutonium was discovered by Glenn T. Seaborg in year 1940 in United States. Plutonium derived its name derived its name from from Pluto, a dwarf planet in the Solar System (then considered the ninth planet)
