A joint IUPAC/IUPAP Working Party (JWP) has confirmed the discovery of the elements with atomic numbers 113, 115, 117 and 118. In accord with IUPAC procedures, the discoverers proposed names as follows:
- nihonium and symbol Nh, for the element with Z = 113,
- moscovium with the symbol Mc, for the element with Z = 115,
- tennessine with the symbol Ts, for the element with Z = 117, and
- oganesson with the symbol Og, for the element with Z = 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.
