(a) ${O^{ - 2}}$ has the highest value of ionic radii as this can be explained on the basis of
(a) ${O^{ - 2}}$ has the highest value of ionic radii as this can be explained on the basis of
$Z/e\,\,\left\{ {\frac{{{\rm{Nucleaus charge}}}}{{{\rm{No}}{\rm{. of electron}}}}} \right\}$
Whereas $Z / e$ ration increases, the size decreases and when $Z / e$ ration decreases the size increases.
