Lastly, and in line with the tradition of honoring a scientist, the name oganesson and symbol Og for element 118 was proposed by the collaborating teams of discoverers at the Joint Institute for Nuclear Research, Dubna (Russia) and Lawrence Livermore National Laboratory (USA) and recognizes Professor Yuri Oganessian (born 1933) for his pioneering contributions to transactinoid elements research. Tennessine is in recognition of the contribution of the Tennessee region of the United States, including Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee at Knoxville, to superheavy element research. Moscovium is in recognition of the Moscow region and honors the ancient Russian land that is the home of the Joint Institute for Nuclear Research, where the discovery experiments were conducted using the Dubna Gas-Filled Recoil Separator in combination with the heavy ion accelerator capabilities of the Flerov Laboratory of Nuclear Reactions. Both are in line with tradition honoring a place or geographical region. Moscovium with the symbol Mc for element 115 and tennessine with the symbol Ts for element 117 were proposed by the discoverers at the Joint Institute for Nuclear Research, Dubna (Russia), Oak Ridge National Laboratory (USA), Vanderbilt University (USA) and Lawrence Livermore National Laboratory (USA). The name nihonium with the symbol Nh for element 113 was proposed by the discoverers at RIKEN Nishina Center for Accelerator-Based Science (Japan) the name came from Nihon which is one of the two ways to say “Japan” in Japanese, and literally mean “the Land of Rising Sun”. The recommendations will be published in the IUPAC journal Pure and Applied Chemistry* ( ). The ending of the names also reflects and maintains historical and chemical consistency: “-ium” for elements 113 and 115 and as for all new elements of groups 1 to 16, “-ine” for element 117 and belonging to group 17 and “-on” for element 118 element belonging to group 18. Keeping with tradition, the newly discovered elements have been named after a place or geographical region, or a scientist. In concordance with and following the earlier reports that the claims for discovery of these elements have been fulfilled, the discoverers have been invited to propose names. Oganesson and symbol Og, for the element 118. Tennessine and symbol Ts, for the element 117, and Moscovium and symbol Mc, for the element 115, Nihonium and symbol Nh, for the element 113, The following names and symbols are officially assigned: Research Triangle Park, NC: On 28 November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name and symbols for four elements: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), respectively for element 113, 115, 117, and 118.įollowing a 5-month period of public review, the names earlier proposed by the discoverers have been approved by the IUPAC Bureau. Brief from the 2023 Summer School on Green Chemistry įacebook Tweet Pin Elements 113, 115, 117, and 118 are now formally named nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og).eTOC Alert ‘Pure and Applied Chemistry’ – May 2023.2023 Nominees for Election of IUPAC Officers, Executive and Science Boards.eTOC ‘Chemistry International’ – July-Sep 2023.Actions Taken by IUPAC Council, The Hague, Netherlands, August 2023.Awardees of the 2023 IUPAC-Zhejiang NHU International Award for Advancements in Green Chemistry.eTOC Alert ‘Pure and Applied Chemistry’ – June 2023 – Special Mary L.eTOC Alert ‘Pure and Applied Chemistry’ – July 2023.
