New names for four elements of the periodic table

Did you check the periodic table lately? Well you need to take a last look to its "old version" as the recently discovered elements are about to take their official names.

Japonese scientist finally proposed to name the 113 element of the periodic table: Nihonium (Nh as in Nihon, a japanese word).
Americans and Russian scientist choose Moscovium as a name for the 115, and it is clear that Moscovium refer to Moscow.
As for the 117 and 118, the first one was given the name Tenessine and the symbol (Ts) as an act of gratitude and appreciation of the great work and research done by the institutions of Tennessee(Oak Ridge National Laboratory, Vanderbilt University and the University of Tennessee at Knoxville). The element number 118 got the name of Oganesson and the symbol (Og) in honor of the Professor Yuri Oganessian.
All these elements were discovered by Russian and American laboratories and even by Asian laboratories but the names given by these institutions will not be valid until it is found conform to the IUPAC rules.
