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 Rhenium was discovered by Masataka Ogawa in year 1925 in Germany. Rhenium derived its name derived its name from from Rhenus, the Latin name for the river Rhine |
