History
| Parameter | Bromine | Radon |
|---|---|---|
| History | The element Bromine was discovered by J. Balard and C. Löwig in year 1825 in France. Bromine derived its name from the Greek bromos, meaning 'stench'. | 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. |
