So far I don't think they have.....I've just not been following it. The periodic table only went to 105 when I was in school for chemistry.

The heaviest elements so far are 115, 117, 118 (moscovium, tennessine, and oganesson).
As is obvious from the chart they need more neutrons for stable elements. U238 is the most stable form of element 92.
By that standard 115 would have to be Mc300 or heavier to be stable. The heaviest and most stable isotope (Mc290) was a decay product of the Tennessine production.
