Question

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 $\mathrm{O}^{2-}$ and $\mathrm{Mg}^{2+}$ are same.
Reason ( R ) : Both $\mathrm{O}^{2-}$ and $\mathrm{Mg}^{2+}$ are isoelectronic species
In the light of the above statements, choose the correct answer from the options given below

Select the correct option:

Both (A) and (R) are true and (R) is the correct explanation of (A)

Both (A) and (R) are true but (R) is not the correct explanation of (A)

(A) is true but (R) is false

(A) is false but (R) is true

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Ionic radius of O²⁻ is more than that of Mg²⁺ Both O²⁻ and Mg²⁺ are isoelectronic with 10 electrons
