4 New Elements Added To The Periodic Table; '113' Named RIKEN

The International Union of Pacific and Allied Chemistry (IUPAC) System finalizes the position of 4 new elements in the periodic. The temporary name of these elements are: ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118).

On December 30, 2015, the IUPAC declared in its observation that the four new elements discovered met the sufficient condition for discovery. These elements were discovered in the Russia, United States and Japan. The name of elements can be taken after the name of discoverers, place, mythological concept, a mineral or country.

This is the first time since 2011 when new elements are added in the periodic table. Last elements added were 114 and 116.

The elements Ununtrium, (Uut or element 113) was discovered in the RIKEN Laboratory of Japan. The research work was headed by Kosuke Morita. TheInternational Union of Pure and Applied Chemistry (IUPAC) and International Union of Pure and Applied Physics (IUPAP) recommended that the permanent name of element Ununtrium, (Uut or element 113) will be RIKEN in the recognition of RIKEN Nishina Center for Accelerator-based Science (RNC).

The RIKEN 113 is the first element and heavy metal in the periodic table discovered in the Asia.

The permanent name of remaining elements 115, 117, 118 will be finalized over couple of months.
