History

History
The element Magnesium was discovered by Joseph Black in year 1755 in United Kingdom. Magnesium derived its name from from Magnesia, a district of Eastern Thessaly in Greece
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
