The International Union of Pure and Applied Chemistry (IUPAC) have added four new elements to the Periodic Table. Following a 5-month public review , the names of elements 113, 115, 117, and 118 were announced on November 28.
The discoverers of the new elements were invited to propose possible names. In keeping with tradition, the elements were named after the locations where they were discovered, or after a scientist who contributed to the study of Chemistry. Here are the official names and symbols approved by the IUPAC:
Nihonium and symbol Nh, for element 113.
Moscovium and symbol Mc, for element 115.
Tennessine and symbol Ts, for element 117.
Oganesson and symbol Og, for element 118.

Four New Elements Added To Periodic Table
The first element in the list, element 113, Nihonium, was discovered at the RIKEN Nishina Center for Accelerator-Based Science in Japan. Its name is derived from the traditional Japanese name of the country “Nihon” meaning “Land of the Rising Sun.”
Element 115, Moscovium was discovered by the researchers at the Joint Institute for Nuclear Research, Dubna, Russia. The experiments were conducted using the Dubna Gas-Filled Recoil Separator combined with the heavy ion accelerator capabilities of the Flerov Laboratory of Nuclear Reactions. In keeping with the tradition of naming after locations, Moscovium was named after the Russian capital city, Moscow.
Element 117 in the Periodic Table also owes its name from a geographical location; in this case, the State of Tennessee. Tennessine was discovered through the joint efforts of researchers at Oak Ridge National Laboratory, Vanderbilt University and the University of Tennessee at Knoxville.
Last but definitely not the least, is element 118 Oganesson. The element was discovered through the combined efforts of researchers at the Joint Institute for Nuclear Research in Dubna, Russia and the Lawrence Livermore National Laboratory Livermore, California.
Oganesson was named in honor of Professor Yuri Oganessian (born April 14, 1933) for his pioneering contributions to transactinoid elements research. Among his many achievements include the discovery of superheavy elements and significant advances in the nuclear physics of superheavy nuclei.
Only Discoverers Currently Allowed To Name Newfound Elements
During the 5-month review, the IUPAC received suggestions, comments, and even petitions from public and large organizations. However, given the current guidelines, only the discoverers are allowed to name the new elements.
Nevertheless, Nihonium, Moscovium, Tennessine, and Oganesson will make fine additions to the Periodic Table. While practical uses for these elements are still further down the road, these four new additions will certainly make Chemistry much more interesting.
