New elements added to chemistry's periodic table New elements added to chemistry's periodic table
(1 day later)
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.
The new elements have temporary titles of ununquadium and ununhexium, but final names have yet to be settled on.The new elements have temporary titles of ununquadium and ununhexium, but final names have yet to be settled on.
