A transition element is defined as one which has incompletely filled d - orbitals in its ground state or in any one of its oxidation states Why are Zn Cd and Hg not regarded as transition metals?

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 student argued that the 3d orbitals will be filled only after the 4s orbital is completely filled in accordance with aufbau principle. Then another student opposed by saying that it is not true for certain elements like Cr and Cu. Write electronic configuration of underset(24)(Cr) and underset(29)(Cu) . Justify your answer.
