The cradle rocks above an abyss, and common sense tells us that our existence is but a brief crack of light between two eternities of darkness
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.
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 new elements have temporary titles of ununquadium and ununhexium.
