History

History
The element Neodymium was discovered by Carl Auer von Welsbach in year 1885 in Austria. Neodymium derived its name from from the Greek neos didymos meaning 'new twin'
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
