The Discovery of Four New Elements in the Periodic Table


The international union of pure and applied chemistry (IUPAC) which is U.S.-centered world authority of chemistry on 28 November 2016 approved the designations and symbols of four new elements. These elements are named as nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), respectively with the atomic number of 113, 115, 117, and 118. The addition of these elements completed the seventh row of the periodic table.

How the elements are named?

IUPAC provided the researchers the rules and guidelines to help them in assigning the names. These names and designations should possess the ancient condition of being named considering a concept of mythology or alike materials, a geographical region or a place, a scientist or a possession of the element. The criteria was the name of the elements must end with "ium", "ine" or "on". This is done to maintain the chronology of naming assuring consistency of elements.

Nihonium (Nh)

According to IUPAC, scientists of Japan’s Riken Nishima center, based on Accelerator science suggested the name as nihonium which also means “Japan”. In Japanese nihonium means the land of rising sun. Researchers discovered the indefinable element in Aug 2012, by taking a thin layer of bismuth and then colliding with zinc nuclei. Similar to other heavy elements, when Nihonium was created, it immediately decayed, eventually changing element 113 as Roentgenium (111).

Moscovium (Mc)

Moscovium element was named and proposed in recognition with the Moscow region and privileges the nuclear research of joint institute which is situated in Russia and Lawrence Livermore National Laboratory in the United States. The element was discovered in 2003 and later announced on Feb 2004. To create moscovium, the scientists assaulted the ions of calcium with the atoms of americium in a cyclotron producing atoms of moscovium.
