2 new elements added to periodic table


June 9, 2011 - London

Memorizing the periodic table just got harder after scientists from the international overseeing committees of physics and chemistry added two new elements to it.

The yet unnamed elements 114 and 116 are both highly radioactive and exist for less than a second before decaying into lighter atoms, reports the BBC.

The table is the official compedium of known elements, organised according to the properties of their atomic structure.

The review was conducted by a joint working party of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP).

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 new elements have temporary titles of ununquadium and ununhexium, but final names have yet to be settled on.

The discovery of both elements has been credited to a collaborative team based at the Joint Institute for Nuclear Research in Dubna, Russia, and Lawrence Livermore National Laboratory in California, US.

Details have been published in the journal Pure and Applied Chemistry.
