History

History
The element Californium was discovered by Lawrence Berkeley National Laboratory in year 1950 in United States. Californium derived its name from from California, where the element was first synthesized
The element Thorium was discovered by Jöns Jakob Berzelius in year 1829 in Sweden. Thorium derived its name derived its name from from Thor, the Scandinavian god of thunder
