Moscowium proposed for 115:

These elements are imho a kind of fake, as no chemical or physical properties can be determined for just a few atom sized quantities .
Of course, 85At and 87Fr have the same issue but these elements are decay products of elements occurring in nature.

I seem to recall that the theoretical limit for doing chemistry is around 10-14 second. (Note that that would make it possible to study the chemistry of hyperatoms since the lifetime of a lambda hyperon is around 10-10 second, permitting the characterization of the chemistry of elements far beyond the current end of the periodic table.)

Provisional names (final approval won't be until around the end of the year but changes seem unlikely):
113 = nihonium, Nh
115 = moscovium, Mc
117 = tennessine, Ts
118 = oganesson, Og

Aw. I really though someone would name a new element after Lemmy Kilmister.

Lemmium, symbol Fu ...

It's official.
