History

History
The element Promethium was discovered by Chien Shiung Wu in year 1945 in United States. Promethium derived its name from from Prometheus of Greek mythology who stole fire from the Gods and gave it to humans
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'
