History
| Parameter | Radon | Gold |
|---|---|---|
| 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 Gold was discovered by Bulgaria in year Before 6000 BCE. Gold derived its name from English word (aurum in Latin). |
