History

History
The element Cerium was discovered by Martin Heinrich Klaproth in year 1803 in Germany and Sweden. Cerium derived its name from from the then recently discovered asteroid Ceres, considered a planet at the time
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'
