Assertion : Zn, Cd and Hg are not considered as transition metals.
Reason :d-orbitals in Zn, Cd and Hg are completely filled, both in ground state and in their available oxidation states.

A

If both (A) and (R) are correct and (R) is the correct explanation of(A).

B

If both (A) and (R) are correct, but(R) is not the correct explanation of (A).

C

If(A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
A
Zn, Cd and Hg are normally not considered as transition metals because d-orbitals are completely filled, hence they do not show the general characteristic properties of the transition elements. Therefore, Zn, Cd and Hg are normally not considered transition metals
