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 Xenon was discovered by William Ramsay in year 1898 in United Kingdom. Xenon derived its name derived its name from from the Greek xenos, meaning 'strange'
