Theory predicts that element 118 would be surrounded by a smear of electrons

Oganesson, also known as element 118, was named for its formal place in the periodic table: the ‘-on’ suffix recognises that it sits at the bottom of the noble gases. But the periodicity of chemical properties has been found to be disrupted for some other superheavy elements. So is oganesson really like the other members of its family?
