History

History
The element Uranium was discovered by Martin Heinrich Klaproth in year 1789 in Germany. Uranium derived its name from from Uranus, the seventh planet in the Solar System
The element Silicon was discovered by Jöns Jacob Berzelius in year 1824 in Sweden. Silicon derived its name derived its name from from the Latin silex, 'flint' (originally silicium)
