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 Gold was discovered by Middle East in year 2500 BC in unknown place. Gold derived its name derived its name from from English word (aurum in Latin)
