Transition elements are usually characterised by variable oxidation states but Zn does not show this property because of :

A

completion of np-orbitals

B

completion of (n-1)d orbitals

C

completion of ns-orbitals

D

inert pair effect

Text Solution

Verified by Experts

The correct Answer is:
B
`Zn={Ar]4s^(2)3d^(10)`
`d` orbitals are completely filled so it shows only `+2` stable oxidation state.
