Expert Solution
Step 1

Interelectronic species are the species that contains same number of electrons. Now, as these ions contains the same number of electrons so, size of these ions will depend upon nuclear charge.

Now, more is the number of protons more will be nuclear charge and hence, more will be attraction for the outermost electron and so, smaller will be the size of the ion.
