History
Name | Radon | Boron |
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 Boron was discovered by L. Gay-Lussac and L.J. Thénard in year 1808 in France and United Kingdom. Boron derived its name from borax, a mineral. |
