The atomic number 113, 115, 117 and 118 now s on occupied by four superheavy chemical elements found by scientists in Japan, Russia and the United States and recognized by the International Union of Pure and Applied Chemistry (IUPAC), the organization that governs chemical nomenclature.
The latest update of the periodic table was held in 2011 with the addition of the 114 (Flerovium) and 116 (Livermorium) who were named in honor of the laboratories were synthesized.
“The chemistry community is eager to see his most prized table finally complete until the seventh row “ he said in a statement Jan Reedijk, President of IUPAC.
These elements have names and temporary symbol because its existence was not proven because not found in nature and decompose in milliseconds, so it must have been created by man to identify some of its properties.
The element 113 is the first discovery awarded to Japan. He was found by scientific Kosuke Morita, at the University of Kyushu in 2012, by bombarding with zinc ions a thin layer of bismuth.
Meanwhile, elements 115, 117 and 118 were discovered by a Russian-American team of scientists from the Joint Institute for Nuclear Research in Dubna (Russia) and the Lawrence Livermore National Laboratory in California (USA).
The latter elements are characterized by decompose in milliseconds be highly heavy and radioactive, so far no uses of the experimental.
In the months ahead should be appointed the new elements so far known as ununtrium, unumpentium, ununseptium and ununoctium .
The new designations must relate scientific words mythological, minerals, countries or .
