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 Silver was discovered by unknown in year 3000 BC in unknown place. Silver derived its name derived its name from from English word (argentum in Latin)
