The extra words in clues gave wordplay leading to {sun, new, inactive, hidden, stranger, radium, Oganessian}, the origins of names of the elements in group 18 of the periodic table, in order of their atomic numbers. Inserting their symbols into down entries would make, respectively: 8 Sa(He)lian, 26 pho(Ne)tic, 6 milit(Ar)ia, 23 ban(Kr)ate, 4 ta(Xe)mes, 2 gu(Rn)ards, 21 gamb(Og)ian. The group number 18 was drawn through the insertion points (any recognisable form of 1 and 8 passing through the right points was accepted). The title referred to 18 as the age of majority and the elements being on the right of the Periodic Table.
