Zn is not considered as a transition element.
Why is zinc not regarded as a transition element? (at np Zn = 30)
Examine the following observation:
Zinc is not regarded as a transition element.

Solution 1
Zinc is not considered a transition element because it does not have partly filled (or incomplete) d-subshell. It has 3d-subshell full filled.
Solution 2
Transition metals show vacant d-orbitals but Zn metal has completely filled d-orbitals.
∴ Zn is not regarded as the transition element.
