Given below are two statements. One is labelled as Assertion and the other is labelled as Reason.
STATEMENT-1 (Assertion): Na+ and Al3+ are isoelectronic but the magnitude of ionic radius of Al3+ is less than that of Na+.
STATEMENT-2 (Reason): The magnitude of effective nuclear charge on the valence electrons in Al3+ is greater than that in Na+.
In the light of the above statements, choose the correct answer from the options given below:
- Both Assertion and Reason are correct and Reason is a correct explanation for the Assertion.
- Both Assertion and Reason are correct but Reason is not a correct explanation for the Assertion.
- Assertion is correct but Reason is incorrect.
