Four New Elements Are Being Added To the Period Table

Four new elements are being added to the period table: Nihonium (element 113), Moscovium (element 114), Tennessine (element 115), and Oganesson (element 118).

Scientists in Japan have managed to make the 113th element of the period table, and have named it after the Japanese word for Japan: “Nihon”. Nihonium will be abbreviated at “Nh” on the periodic table.

Researchers at the Riken Institute, lead by Kyushu University’s Professor Kosuke Morita, successfully created the superheavy synthetic element. They secured the naming rights after re-creating the element three times in 2004, 2005, and 2012.

A U.S.-Russian team claimed to have discovered the element earlier than the Riken team, but a working group created by the International Union of Pure and Applied Chemistry and by the International Union of Pure and Applied Physics concluded that the Riken team discovered the 113th element first.

Moscovium and Tennesine have also been named in honor of their places of discovery. They have been found by the efforts of the Joint Institution for Nuclear Research (Russia), Oak Ridge National Laboratory (USA), Vanderbilt University (USA), and Lawrence Livermore National Laboratory (USA). Moscovium has been named in honor of Moscow at the Joint Institute For Nuclear Research. The experiments were conducted using the Dubna Gas-Filled Recoil Separator, along with the heavy ion accelerator of the Flerov Laboratory of Nuclear Reactions. Tennessine is in honor of the U.S state, Tennessee, where Oak Ridge National Laboratory, Vanderbilt University, and Lawrence Livermore National Laboratory are all at, as well as the superheavy element research.


The collaborating teams at the Joint Institute for Nuclear Research (Russia) and Lawrence Livermore National Laboratory (USA) discovered Oganesson. Instead of honoring it’s place of discovery, Oganesson is in honor of Professor Yuri Oganessian (1933) for his major contributions to transactinoid elements research. His achievements include the discovery of superheavy elements and great advances in nuclear physics of superheavy nuclei.
