New Elements in Periodic Table

The latest heavy elements 114 and 116 will get their place and name in the periodic table, as proposed by the Union of Pure and Applied Chemistry (IUPAC). It was suggested to identify the element 114 as Flerovium and the element 116 as Livermorium. The elements 114 and 116 were officially accepted in June 2011 as heaviest elements in the periodic table, more than 10 years later than they were discovered by the scientists from the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore chemists. The element Flerovium (atomic symbol Fl) was chosen to honor Flerov Laboratory of Nuclear Reactions, where superheavy elements, including element 114, were synthesized.

Georgiy N. Flerov (1913-1990) was a renowned physicist who discovered the spontaneous fission of uranium and was a pioneer in heavy-ion physics. He is the founder of the Joint Institute for Nuclear Research. In 1991, the Flerov Laboratory of Nuclear Reactions (FLNR) laboratory was named after Flerov. The element Livermorium (atomic symbol Lv) was chosen to honor Lawrence Livermore National Laboratory (LLNL) and the city of Livermore, Calif. A group of researchers from the this laboratory with the scientists from the Flerov Laboratory of Nuclear Reactions, initiated research in Dubna on the synthesis of superheavy elements, including element 116. Another element Lawrencium – numbered 103 in the periodic table — was already named for LLNL’s founder E.O. Lawrence. The newly created heavy elements 114 and 116 generate a hope that area of the chemical periodic table in which new heavy elements are involved would be stable or last long enough for applications to be found. New names were submitted to IUPAC in October and are currently available on the public domain. The new names will become official after five months when the public comment period will be over.
