The two new elements, which have the atomic numbers 114 and 116, were discovered by scientists in the U.S. and Russia. iStockNames have been proposed for the two heaviest known chemical elements.
The elements, which have the atomic numbers 114 and 116, were officially recognized in June by the International Union of Pure and Applied Chemistry, the organization that addresses international issues involving the chemical sciences, including nomenclature.
Scientists at the Lawrence Livermore National Laboratory-Dubna collaboration, which discovered the two elements, have proposed that element 114 be named flerovium and given the atomic symbol Fl to honour the Flerov Laboratory of Nuclear Reactions in Dubna, Russia, where a number of super-heavy elements, including element 114, were made.
They propose that element 116 be named livermorium and be given the atomic symbol Lv to honour Lawrence Livermore National Laboratory in Livermore, Calif.

The two names were announced Thursday by IUPAC president Nicole Moreau.
IUPAC said the names have been approved by its inorganic chemistry division.
Next, it will issue a provisional recommendation and allow five months for public comments before it heads for final approval by the IUPAC council.
While the heaviest element has an atomic number of 116, the official periodic table still contains only 114 elements because elements 113 and 115 haven't been officially accepted yet.
