Unveiling the unpronounceable

Two new elements have been added to the Periodic Table - welcome ununquadium and ununhexium. The good news is that these are only temporary names. The new elements have been added to the periodic table after a three-year review conducted by a joint working party of the International Union of Pure and Applied Chemistry and the International Union of Pure and Applied Physics. In recent years, there have been several claims for the discovery of new chemical elements at positions 113, 114, 115, 116 and 118 on the periodic table. However the working party concluded that only elements 114 and 116 fulfilled criteria for official inclusion in the Periodic Table. The others, as yet, do not.
