WebThe Na + ion is significantly smaller than the neutral Na atom because the 3 s1 electron has been removed to give a closed shell with n = 2. The Na − ion is larger than the parent Na atom because the additional electron produces a 3 s2 valence electron configuration, while the nuclear charge remains the same.
