History

History
The element Fluorine was discovered by André-Marie Ampère in year 1886 in France. Fluorine derived its name from from the Latin fluere, meaning 'to flow'
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
