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

Explanation

Zn, Cd and Hg have (n-1) `d^(10)ns^(2)` electron configuration in their atoms and `(n-1)d^(10)ns^(0)` electron 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.
