Ununquadium and Ununhexium


Don’t know what these words are? Soon you will have to memorize them, that is if you really want to know all periodic elements by heart. It seems like after three years of review our beloved chemists and physicists finally decided that they will be adding element 114 and 116 to the periodic table of elements.

Officially these elements are still un-named, but Ununquadium and Ununhexium is what they have been called.  Most of the credit of these two elements goes to Russian team, so don’t be surprised if they are named in Russian.

The final prove of these two elements came from Joint Institute for Nuclear Research (JINR) in Dubna, Russia and Lawrence Livermore National Laboratory in California.

Here is the approved paper:

Discovery of the elements with atomic numbers greater than or equal to 113 (IUPAC Technical Report)

And the abstract:

Abstract: The IUPAC/IUPAP Joint Working Party (JWP) on the priority of claims to the discovery of new elements 113–116 and 118 has reviewed the relevant literature pertaining to several claims. In accordance with the criteria for the discovery of elements previously established by the 1992 IUPAC/IUPAP Transfermium Working Group (TWG), and reinforced in subsequent IUPAC/IUPAP JWP discussions, it was determined that the Dubna-Livermore collaborations share in the fulfillment of those criteria both for elements Z = 114 and 116. A synopsis of experiments and related efforts is presented.
