Since isoelectronic atoms have the same electronic configuration and valence electron number but different atomic radii do they have the same of different electronegativities?

Since elements that are more electronegative are more likely to gain electrons and atoms that are isoelectronic have the same number of electrons, the electronegativity of the atoms should be equivalent. For example an atom with 10 electrons shouldn't have more electronegativity than another atom with 10, since they both have the same number of electrons they should equally be willing to accept other electrons.

If im reading your question right, then i believe that their electronegativities are subject to change if they lose or gain an e. if they gain an e, it's easy for them to lose and if they lose an e than they are more likely to gain an e. Therefore their electronegativities change
