History

History
The element Barium was discovered by Carl Wilhelm Scheele in year 1808 in United Kingdom. Barium derived its name from from the Greek barys, meaning 'heavy'
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
