Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The ionic radii of $\displaystyle \mathrm{O}^{2-}$ and $\displaystyle \mathrm{Mg}^{2+}$ are same.
Reason (R) : Both $\displaystyle \mathrm{O}^{2-}$ and $\displaystyle \mathrm{Mg}^{2+}$ are isoelectronic species.
In the light of the above statements, choose the correct answer from the options given below.
Official answer
(4)
(A) is false but (R) is true.
