transitional element
"an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell".
Explanation:
The electronic configurations of Zn, Cd and Hg are represented by the general formula (n-1)d10 ns2.
The orbitals in these elements are completely filled in the ground state as well as in their common oxidation states. Therefore, they are not regarded as transition elements.
