Names for New Elements 113, 115, 117 and 118 Now Approved

On the 28 November, after a five-month period of public review, the International Union of Pure and Applied Chemistry (IUPAC) approved the name and symbols for four elements: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), respectively for element 113, 115, 117, and 118.

In concordance with and following the earlier reports that the claims for discovery of these elements have been fulfilled, the discoverers have been invited to propose names. Keeping with tradition, the newly discovered elements have been named after a place or geographical region, or a scientist. The ending of the names also reflects and maintains historical and chemical consistency: “-ium” for elements 113 and 115 and as for all new elements of groups 1 to 16, “-ine” for element 117 and belonging to group 17 and “-on” for element 118 element belonging to group 18. Complete information on these new elements can be found at IUPAC´s page.
