4 new superheavy elements added to the Periodic Table, the first to be added since 2011, giving them the four atomic numbers of 113, 115, 117 and 118.
Four new elements will join the periodic table of the elements, the International Union of Pure and Applied Chemistry (IUPAC) announced on December 30th.
Scientists created the new elements and verified that the production could be reproduced.
Right now they’ve been given temporary names – ununtrium (113), ununpentium (115), ununseptium (117) and ununoctium (118).
Credit for element 113 was given to RIKEN team in Japan, for elements 115 and 117 to the Oak Ridge National Laboratory in Tennessee and for element 118 to both the Joint Institute for Nuclear Research in Dubna, Russia, and the Lawrence Livermore National Laboratory in California.
Professor Polly Arnold, from the University of Edinburgh, said:
“The new elements confirm the structure of the periodic table beautifully.”
Professor Jan Reedijk, president of the Inorganic Chemistry Division of IUPAC, said:
“The chemistry community is eager to see its most cherished table finally being completed down to the seventh row.”
