Newest elements on periodic table receive names, symbols.

Four new elements now have names.

In December, the International Union of Pure and Applied Chemistry officially recognized the discovery of elements 113, 115, 117 and 118, filling out the seventh row of the periodic table (SN: 2/6/16, p. 7). As is traditional in chemistry, the naming rights went to the discoverers: Scientists at RIKEN in Wako, Japan, named element 113, and a Russian-U.S. collaboration named the others.

Element 113 is dubbed "nihonium" with the chemical symbol Nh. Its name comes from the Japanese word Nihon, or "Land of the Rising Sun," a name for Japan.

Element 115 will receive the moniker "moscovium," shortened to Me, after the Moscow region, home to the Joint Institute for Nuclear Research in Dubna, where the element was discovered in collaboration with researchers at Lawrence Livermore National Laboratory in California and Oak Ridge National Laboratory in Tennessee.

Tennessee also gets a periodic table shout-out. The name for element 117 is "tennessine," after the home state of Oak Ridge and Vanderbilt University, which was also involved in the discovery. It will bear the symbol Ts.

Element 118 will be named oganesson, or Og, after Yuri Oganessian, a Russian physicist who contributed to the discovery of several superheavy elements.

After a five-month public review period and approval by the IUPAC, the names will become official.
