Which one is the correct decreasing order of the ionic radii of the ions?
N3- > O2-> F- > Na+
N3-> Na+> O2- > F-
Na+ >O2-> N3-> F-
Na+> F-> O2->N3-
The ionic radii of N3-, O2-, F- and Na+ follow the order
N3- > O2- > F- > Na+
N3- > Na+ > O2- > F-
Na+ > O2- > N3- > F-
O2- > F- > Na+ > N3-
A.
N3- > O2- > F- > Na+
All the given ions are isoelectronic. In case of isoelectronic species as atomic number increases ionic radii of ions decreases. Therefore,
7N3- > 8O2- > 9F- > 11Na+
