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 Selenium was discovered by Jöns Jakob Berzelius in year 1817 in Sweden. Selenium derived its name derived its name from from the Greek selene, meaning 'moon'
