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 Tantalum was discovered by Anders Gustaf Ekeberg in year 1802 in Sweden. Tantalum derived its name derived its name from from King Tantalus, father of Niobe from Greek mythology
