History

History
The element Americium was discovered by Glenn T. Seaborg in year 1944 in United States. Americium derived its name from from The Americas, as the element was first synthesized on the continent, by analogy with europium
The element Bismuth was discovered by Claude François Geoffroy in year 1400 in unknown place. Bismuth derived its name derived its name from from German word, now obsolete
