History
History |
The element Dysprosium was discovered by Lecoq de Boisbaudran in year 1886 in France. Dysprosium derived its name from from the Greek dysprositos, meaning 'hard to get' |
The element Cerium was discovered by Martin Heinrich Klaproth in year 1803 in Germany and Sweden. Cerium derived its name derived its name from from the then recently discovered asteroid Ceres, considered a planet at the time |
