Four new chemical elements have been officially named.

Late last year, the scientific community announced the confirmation of the discovery of four new elements, nos. 113, 115, 117 and 118 were officially added to the periodic table of elements.
, November 30, Beijing time, December 1, the International Union of Pure and Applied Chemistry (IUPAC) in the United States Research Trangle Park in North Carolina officially announced that the four newly discovered elements were named:
113: Niho
nium (Nh)

115th: Moscovium (Mc)
117: Tennessean (Ts)
118: Oganesson (Og
According to tradition, newly discovered elements are either named after geographical locations or by scientists, while the discoverers of new elements have naming priority. Element 113 was discovered by the Japanese Institute of Science and Chemchem, the first new element found in Asia. As a result, Japanese scientists were named Niho
nium (Nh), which means Nihon, the Japanese word for "the rising earth of the sun", another Japanese term.
115, a joint discovery by Russian and American scientists, was named Moscovium (Mc), taken in Moscow. Element 117 Tennessine (Ts), the co-discoverer of this element, is located at Oak Ridge National Laboratory in Tennessee, USA. Element 118 Oganesson (Og) is a tribute to Russian scientist Yuri Oganessian, a pioneer in the study of heavy elements.
addition to Oak Ridge National Laboratory, Lawrence Liverpool National Laboratory in the United States is also named, in 2011 named element 116 Livermorium (Lv), in recognition of Lawrence Liverpool National Laboratory.
