History

History
The element Gadolinium was discovered by Jean Charles Galissard de Marignac in year 1880 in Switzerland. Gadolinium derived its name from from Johan Gadolin, chemist, physicist and mineralogist
The element Magnesium was discovered by Joseph Black in year 1755 in United Kingdom. Magnesium derived its name derived its name from from Magnesia, a district of Eastern Thessaly in Greece
