History
History |
The element Mendelevium was discovered by Lawrence Berkeley National Laboratory in year 1955 in United States. Mendelevium derived its name from from Dmitri Mendeleev, chemist and inventor |
The element Uranium was discovered by Martin Heinrich Klaproth in year 1789 in Germany. Uranium derived its name derived its name from from Uranus, the seventh planet in the Solar System |
