History
| Parameter | Cesium | Radon |
|---|---|---|
| History | The element Cesium was discovered by R. Bunsen and R. Kirchhoff in year 1860 in Germany. Cesium derived its name from the Latin caesius, meaning 'sky blue'. | 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. |
