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 Chromium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Chromium derived its name derived its name from from the Greek word chroma, meaning 'color' |
