Assertion: Transitio metals show variable valence.
Reason : Due to a large energy difference bteween the `ns^(2)` and `(n - 1)d` electrons.

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:
C
The assertion is correct but the reason is false. Actually transition metal show variable valency due to very small difference between the ns^2` and `(n - 1)d` electrons, Therefore, assertion is correct but reason is false.
