Reference: Science: Four Elements on Periodic Table Getting New Names

From the Official Announcement From the International Union of Pure and Applied Chemistry (IUPAC)

Following earlier reports that the claims for discovery of these elements have been fulfilled, the discoverers have been invited to propose names and the following are now disclosed for public review:
Nihonium and symbol Nh, for the element 113,
Moscovium and symbol Mc, for the element 115,
Tennessine and symbol Ts, for the element 117
Oganesson and symbol Og, for the element 118.
The IUPAC Inorganic Chemistry Division has reviewed and considered these proposals and recommends these for acceptance. A five-month public review is now set, expiring 8 November 2016, prior to the formal approval by the IUPAC Council.

Finally, laboratories are already working on searches for the elements in the 8th row of the periodic table, and they are also working to consolidate the identification of copernicium and heavier elements. To be able to evaluate this work, IUPAC and the International Union of Pure and Applied Physics (IUPAP) are currently reviewing the selection principle and operations of a future Joint Working Party (JWP) and as soon as these principles have been decided a new group will be formed. This new JWP will review new claims and the consistency of new results with those already evaluated by earlier JWPs.
