The ions $O^{2 -}, F^{-}, Na^{+}, Mg^{2 +}$ and $Al^{3 +}$ are isoelectronic. Their ionic radii show:

Options:

Answer:

Solution:

Amongst isoelectronic species, ionic radii of anion is more than that of cations. Further size of anion increase with increase in -ve charge and size of cation decrease with increase in $+$ ve charge. Hence ionic radii decreases from $O^{-}$ to $Al^{3 +}$
