On 30 May 2012, IUPAC officially approved the name flerovium, with symbol Fl, for the element of atomic number 114 and the name livermorium, with symbol Lv, for the element of atomic number 116. The names and symbols were proposed by the collaborating team of the Joint Institute for Nuclear Research (Dubna, Russia) and the Lawrence Livermore National Laboratory (Livermore, California, USA) to whom the priority for the discovery of these elements was assigned last year. The IUPAC recommendations presenting these names is to appear in the July 2012 issue of Pure and Applied Chemistry.
The name flerovium, with symbol Fl, lies within tradition and honors the Flerov Laboratory of Nuclear Reactions in Dubna, Russia, where the element of atomic number 114 was synthesized. Georgiy N. Flerov (1913–1990) was a renowned physicist, an author of the discovery of the spontaneous fission of uranium in 1940 (with Konstantin A. Petrzhak), a pioneer in heavy-ion physics, and founder in 1957 of the Laboratory of Nuclear Reactions, part of the Joint Institute for Nuclear Research.
The name livermorium, with the symbol Lv, for the element with atomic number 116 is again in line with tradition and honors the Lawrence Livermore National Laboratory. A group of researchers at this laboratory took part in the work carried out in Dubna on the synthesis of superheavy elements, including element 116.
"These names honor not only the individual contributions of scientists from these laboratories to the fields of nuclear science, heavy element research, and superheavy element research, but also the phenomenal cooperation and collaboration that has occurred between scientists in these two countries," said Bill Goldstein, associate director of LLNL's Physical and Life Sciences Directorate.
Priority of claims to the discovery of the elements of atomic numbers 114 and 116 was determined by a Joint Working Party of independent experts drawn from IUPAC and the International Union of Pure and Applied Physics. The group's report was published in Pure and Applied Chemistry in July 2011. A newly appointed Joint Working Party has now begun work to assign priority for the discovery of elements 113, 115, 117, 118, and heavier elements.
