Hi there!
Order of Ionic radii :
Al³+ > Mg²+ > Na+ > F- > O²- > N³-
As the magnitude of positive charge decreases the ionic radii of the species increases, thus cations are smaller in size then anions and, among the cations, ions having high positive charge have small ionic radii.
Similarly, among the anions, ions having high negative charge have large ionic radii.
[ Thank you! for asking the question. ]
Hope it helps! :D

Answer:
Al³+<Mg²+<Na+<F-<O²-<N³-
Explanation:
Since the number of electrons are same ,the ionic size decreases with increase in nuclear charge . Therefore ,the ions can be arranged in increasing order of ionic radii as.
