The ionic radii of N3−N^{3 -}, O2−O^{2 -}, F−F^{-} and Na+Na^{+} follow the order

A

N3−>O2−>F−>Na+N^{3 -} > O^{2 -} > F^{-} > Na^{+}

B

N3−>Na+>O2−>F−N^{3 -} > Na^{+} > O^{2 -} > F^{-}

C

Na+>O2−>N3−>F−Na^{+} > O^{2 -} > N^{3 -} > F^{-}

D

O2−>F−>Na+>N3−O^{2 -} > F^{-} > Na^{+} > N^{3 -}

Answer

N3−>O2−>F−>Na+N^{3 -} > O^{2 -} > F^{-} > Na^{+}

Explanation

Solution

As effective nuclear charge on Na+Na^{+} is maximum. It has smallest size.
