Q. Out of $N , O , Ne , Na$ and $Na ^{+},$ which of these species will have the maximum and minimum ionization energy respectively:

Classification of Elements and Periodicity in Properties

Solution:

$Na ^{+}$ and $Ne$ are isoelectronic but $Na ^{+}$ has more protons. So, its $I.E.$ is highest.

$Na$ is alkali metal with a very low $I.E.$
