History

History
The element Nobelium was discovered by Joint Institute for Nuclear Research in year 1958 in Sweden and United States. Nobelium derived its name from from Alfred Nobel, chemist, engineer, innovator, and armaments manufacturer
The element Americium was discovered by Glenn T. Seaborg in year 1944 in United States. Americium derived its name derived its name from from The Americas, as the element was first synthesized on the continent, by analogy with europium
