Flerovium is a chemical element with the atomic number 114 and the element symbol Fl. It is one of the Transactinoiden.

History

Flerovium was produced probably the first time in 1999 in the Joint Institute for Nuclear Research, Dubna at (Russia) by scientists at the Institute and the Lawrence Livermore National Laboratory. The discovery was confirmed in June 2011 by the IUPAC, thus this element officially finds its way into the periodic table of elements. On 30 May 2012, the proposed December 1, 2011 name was adopted by the IUPAC. Until that time, it was Ununquadium, symbol Uuq. The new name was given in honor of the Russian physicist Georgi Fljorow ( English transcription Flerov ).

Properties

The most stable of the previously known Flerovium isotopes 289Fl, having 2.7 seconds long in comparison to the adjacent elements in the periodic table half-life. This is because it is a so-called magic number of nuclear physics at the atomic number 114; from completed Nukleonenschalen in the core such nuclides are particularly stable. When not yet been synthesized isotope 298Fl it would be a doubly magic nucleus, that is, the number of neutrons would be a magic number. It is therefore expected that the half-life of this isotope is even higher.
