Consider the following species :

$$N^{3-},O^{2-},F^{-},Na^{+},Mg^{2+},\; and\; Al^{3+}$$

(a) What is common in them?

(b) Arrange them in the order of increasing ionic radii.

##### Solution :-

(a) The species that are given are having an equal number of electrons i.e. 10 electrons. So, they are isoelectronic species.

(b) Arrangement of the given ions according to their increasing order of ionic radii is:

$$Al^{3+} < Mg^{2+} < Na^{+} < F^{-} < O^{2-} < N^{3-}$$
