For all the chem wonks out there: The periodic table is expected to get new four elements on its seventh row: moscovium, nihonium, oganesson and tennessine. Earlier this year, scientists announced the discovery of elements 113, 115, 117 and 118, but their names and symbols were not proposed until yesterday.
The International Union of Pure and Applied Chemistry, the body that oversees global chemical terminology, opened a public comment period this week for the recommended names, which were proposed by the labs that discovered the super-heavy elements. Moscovium (Mc) is being recommended for element 115 in recognition of the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, which was credited along with scientists at Lawrence Livermore National Laboratory for discovering it and element 118. Tennessine (Ts) is being proposed for element 117 to recognize the contribution of Tennessee-based Oak Ridge National Laboratory and Vanderbilt University for their research on super-heavy elements. Lawrence Livermore National Laboratory; JINR; the University of Nevada, Las Vegas; and Vanderbilt University also were credited with the discovery of element 117. The proposed name for element 118 is oganesson (Og) in honor of Russian scientist Yuri Oganessian, who discovered many of the heavy elements on the periodic table. Nihonium (Nh) is being proposed for element 113 because of its discovery by the RIKEN Nishina Center for Accelerator-Based Science in Japan. It is the first element discovered in an Asian country, according to IUPAC. Nihon is one of two ways to say "Japan" in Japanese, and means "the land of the rising sun." The names are expected to be approved by the IUPAC Council later this year after a five-month review period. "I'm proud of all of the hard work that this group has done over the years performing these experiments," said Dawn Shaughnessy, LLNL's principal investigator for the Heavy Element Group. "It's a huge accomplishment for the entire group that we are recognized for our efforts in accomplishing these highly difficult experiments and for the years of work it takes to successfully create a new chemical element." _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
