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 Radon was discovered by Friedrich Ernst Dorn in year 1900 in Germany. Radon derived its name derived its name from From radium, as it was first detected as an emission from radium during radioactive decay
