Speculation on new element names
A panel commentary in Nature Chemistry Commentary speculates upon the names that might be proposed for the four new elements in the periodic table. Worth a read, but we’ll have to wait a while longer yet.
Abstract: “Of all the things humans can bestow names upon, new chemical elements are about the rarest. Our group of periodic table experts attempts to read the tea leaves and predict the names for elements 113, 115, 117 and 118.”

Four elements to get names
The International Union of Pure and Applied Chemistry (IUPAC) announced IN January 2016 that the identification of the four new elements with atomic numbers 113, 115, 117, and 118 is verified and that the discoverers of elements 113, 115, 117, and 118 are invited to suggest names.
Element 113 has a temporary working (systematic) name and symbol: ununtrium, Uut. It was discovered by the RIKEN collaboration team in Japan who fulfilled the criteria for element Z=113.

Welcome back element 118 (ununoctium)
Experiments conducted at the Flerov Laboratory of Nuclear Reactions (Joint Institute for Nuclear Research) at Dubna in Russia indicate that element 118 (ununoctium, Uuo) was produced. Not too much though, one atom in the spring of 2002 and two more in 2005.1, 2
The 2002 experiment involved firing a beam of 4820Ca at 24998Cf. The experiment took 4 months and involved a beam of 2.5 x 1019 calcium ions to produce the single event believed to be the synthesis of 294118Uuo.
