2 New Elements in the Periodic Table: Flerovium & Livermorium


The President of IUPAC, Professor Nicole J. Moreau announced the proposed names for the elements with atomic numbers 114 and 116 at the Closing Ceremony of the International Year of Chemistry in Brussels on December 1, 2011.

On May 1,  a Joint IUPAC-IUPAP Working Party assigned the priorities for the discoveries of these elements (Pure Appl. Chem., Vol. 83, No. 7, pp. 1485–1498, 2011, http://dx.doi.org/10.1351/PAC-REP-10-05-01) to collaborative work between scientists from the Joint Institute for Nuclear Research in Dubna, Russia and from the Lawrence Livermore National Laboratory, California, USA (hereinafter referred to as the Dubna-Livermore collaborations).

Following the procedure laid down by IUPAC the scientists involved in the collaboration were invited to propose names for the elements.

With Professor Yuri Oganessian as spokesperson the collaborators have proposed the name flerovium (symbol Fl) for element number 114 and the name livermorium (symbol Lv) for that with number 116.

These proposed names have now also been examined and approved by the Inorganic Chemistry Division (Division II) of IUPAC which clears the way for IUPAC to issue a Provisional Recommendations document. These Provisional Recommendations will be made available in the very near future for Public Comment for five months and will also be sent to expert referees.

At the end of the Public Comment period, the Inorganic Chemistry Division will review the comments made and either revise the Recommendations or recommend approval by the IUPAC Council. After approval by the IUPAC Council or by the IUPAC Bureau which, in this case, has been delegated to do so, the Recommendations of the names and symbols will be published in the IUPAC Journal, Pure and Applied Chemistry.
