Periodic table in December 2015

In December the year 2015, the International Union of Pure and Applied Chemistry (IUPAC) name unofficially to elements with atomic numbers 113, 115, 117, and 118. The fourth element is not found naturally in nature, but rather should be made/synthesized in the laboratory. Because these elements decay within a few seconds, its existence is quite difficult to be confirmed.

Four elements has the unofficial name i.e. no. Atom 113 Ununtrium (Uut)-, 115 Ununpentium (Uup)-,-117 Ununseptium (Uus), and 118 Ununoctium (Uuo)-.

On December 2, 2016, IUPAC announces the name of the 4 elements. Three elements named after the location of the first research institutions make these elements, i.e. Tennessine (Tennessee/State in the United States), Nihonium (Japan) and Moscovium (Moscow). While the 1 item terispirasi from the nuclear Professor Yuri Oganessian so named Oganesson. Consecutively, the official name is 113-Nihonium (Nh), 115-Moscovium (Mc), 117-Tennessine (Ts), and 118-Oganesson (Og).

And we are still looking forward to the existence of a new element discovered by researchers of Indonesia, so the IUPAC recognizes and gave it the name Indonesium (Id).
