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 Actinium was discovered by Friedrich Oskar Giesel in year 1899 in France. Actinium derived its name derived its name from from the Greek aktis, 'ray'
