(a) Nuclear Charge (Z) Because although all three elements have same number of electrons but inside nucleus the number of protons in unequal.In case of F- it is having only 9 proton and 10 electron so size will expand liitle.In case of Ne it has 10 proton and 10 electron but will have size smaller than...
