The size of isoelectronic species decreases with increasing nuclear charge. Hence, the order of ionic radii of N3-, O2- and F-is as: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/c99f2f4c9e57b49b99f3fc396b0624cb-.png" />

Q. The ionic radii of isoelectronic species $N^{3 -}, O^{2 -}$ and $F^{-}$ are in the order

1.36, 1.40, 1.71

1.36, 1.71, 1.40

1.71, 1.40, 1.36

1.71, 1.36, 1.40

The size of isoelectronic species decreases with increasing nuclear charge. Hence, the order of ionic radii of $N^{3 -}, O^{2 -}$ and $F^{-}$ is as:
