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 order of increasing ionic radii.

Text Solution

Verified by Experts

These species are isoelectronic to each other.
b) We know that in isoelectronic species, larger the positive charge, smaller is the ionic radii.
Therefore, the increasing ionic radii of these species is as follows:
`Al^(3+)ltMg^(2+)ltF^(-)ltO^(2-)ltN^(3-)`
