Two new elements have been added to the periodic table after a three-year review by the governing bodies of chemistry and physics. | Two new elements have been added to the periodic table after a three-year review by the governing bodies of chemistry and physics. |
The elements are currently unnamed, but they are both highly radioactive and exist for less than a second before decaying into lighter atoms. | The elements are currently unnamed, but they are both highly radioactive and exist for less than a second before decaying into lighter atoms. |

In recent years, there have been several claims by laboratories for the discovery of new chemical elements at positions 113, 114, 115, 116 and 118 on the periodic table. | In recent years, there have been several claims by laboratories for the discovery of new chemical elements at positions 113, 114, 115, 116 and 118 on the periodic table. |
The working party concluded that elements 114 and 116 fulfilled criteria for official inclusion in the table. The others, as yet, do not. | The working party concluded that elements 114 and 116 fulfilled criteria for official inclusion in the table. The others, as yet, do not. |
