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 Palladium was discovered by William Hyde Wollaston in year 1803 in United Kingdom. Palladium derived its name derived its name from from the then recently discovered asteroid Pallas, considered a planet at the time
