History

History
The element Zirconium was discovered by Martin Heinrich Klaproth in year 1789 in Germany. Zirconium derived its name from from Persian Zargun, 'gold-colored'; German Zirkoon, 'jargoon'
The element Curium was discovered by Glenn T. Seaborg in year 1944 in United States. Curium derived its name derived its name from from Pierre Curie, a physicist, and Marie Curie, a physicist and chemist, named after great scientists by analogy with gadolinium
