History

History

The element Hafnium was discovered by Dirk Coster in year 1923 in Denmark. Hafnium derived its name from from Hafnia, the New Latin name for Copenhagen

The element Zirconium was discovered by Martin Heinrich Klaproth in year 1789 in Germany. Zirconium derived its name derived its name from from Persian Zargun, 'gold-colored'; German Zirkoon, 'jargoon'
