History

History
The element Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Beryllium derived its name from from beryl, a mineral
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
