The element 118, Oganesson, which currently holds the last position in the periodic table has been first synthesized in 2002 and added to the periodic table in 2015 (https://en.wikipedia.org/wiki/Oganesson).
Will there be any serious claims this year that a new element with a higher atomic number is synthesized? The claim has to be published in a peer-reviewed journal and mentioned on the relevant Wikipedia's page: https://en.wikipedia.org/wiki/Extended_periodic_table#Searches_for_undiscovered_elements

1.00@MatthewLeong If paper is published, I expect that it will be mentioned on Wikipedia fairly soon. The only scenario under which I can imagine that the paper is published and not mentioned on Wikipedia is if it's quickly retracted or if it's very obscure for some reason. In the first case, I think it's ok to resolve to NO, and in the second I don't see how I would find out about this claim anyway.
If there's a complicated situation, like there's a claim and an edit war on Wikipedia regarding whether to mention it, I'll resolve to N/A. I don't think this is very likely.

@OlegEterevsky For some reason the first comment didn't show, so I though it was lost and answered again :(
