This will take five months, after which the names and symbols will be approved by the Council of the international union. Pioneers will now have the right to come up with the names of the elements and the traditional two-letter notation. The International Union of Pure and Applied Chemistry (IUPAC) awarded the verified elements numbered 115, 117 and 118 to scientists from the Joint Institute for Nuclear Research in Dubna, Moscow Region, and Livermore National Laboratory in California. Researchers from the United States also insist on their priority in the discovery of a new element. The discovery of three of these elements is attributed to the joint Russian-American research team, and the priority in the discovery of the 113th element is recognized by the Japanese.Īs reported by 3 January 'Echo of Moscow' Director of the Institute, Academician of the Russian Academy of Sciences Viktor Matveev, the decision of international experts to transfer the right to 113 element to Japanese scientists from the Riken Institute for Physical and Chemical Research was unexpected for Russian scientists.Īccording to Matveyev, this is a preliminary decision, and the Russians still have time to confirm their rights. This is the first expansion of the table since 2011 of the year, and now the seventh row of the table is completely full.
