Ununpentium new element in the periodic table
Element 115 was synthesized again, a decade after it was discovered, and may now meet the official requirements to get into the periodic table of the elements.
If so, it will rank 115th among the flerovium (114) and livermorium (116), recognized a couple of years ago.
Element 115 has now been produced in the laboratory by a team from the University of Lund (Sweden), in collaboration with German experts. Is superheavy (with atomic number greater than 112) and disintegrates immediately.
It had been discovered in 2003 by Russian and American scientists who managed to create a few atoms of ununpentium (disintegrated in milliseconds).
But the finding was not sufficient for the assembly of the International Union of Pure and Applied Physics (IUPAP) and the corresponding Chemistry (IUPAC) accept it in the periodic table, waiting for the synthesis experiment was reproduced and confirmed committee .
