History
| Parameter | Radon | Neodymium |
|---|---|---|
| History | The element Radon was discovered by E. Rutherford and R. B. Owens in year 1899 in Germany. Radon derived its name From radium, as it was first detected as an emission from radium during radioactive decay. | The element Neodymium was discovered by C. A. von Welsbach in year 1885 in Austria. Neodymium derived its name from the Greek neos didymos meaning 'new twin'. |
