Assertion: The atomic radii of calcium is smaller than sodium
Reason: Calcuim has a lower nuclear charge than sodium.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Assertion : False
The atomic radii of calcium is bigger than sodium as calcium has one extra shell.
Reason : False
