Name the d-block elment which do not have partially filled d-orbitals in their or in their simple ions

Answer

Zn, Cd and `Hg` have `(n-1)d^(10)ns^(2)` electron configurtation in their atoms and `(n-1) d^(10) ns^(0)` electrons configuration in their most stable simple ions i.e. `M^(2+)` . So They do not have partially filled d-orbitals in their atoms or in their Simple ions.
