Q. The ionic radii $(\mathring{A} )$ of $C^{4-}$ and $O^{2-}$ respectively are $2.60$ and $1.40$. The ionic radius of the isoelectronic ion $N^{3-}$ would be

J & K CETJ & K CET 2006

Solution:

$ C^{4-},N^{3-} $ and $ O^{2-} $ are isoelectronic species. The ionic radius of isoelectronic species decreases with increase the nuclear charge. Hence, the order of ionic radius is
