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 Gadolinium was discovered by Jean Charles Galissard de Marignac in year 1880 in Switzerland. Gadolinium derived its name derived its name from from Johan Gadolin, chemist, physicist and mineralogist
