Account for the following :
Zn is not considered as a transition element.
Why is zinc not regarded as a transition element? (at np Zn = 30)
Zinc is not considered a transition element because it does not have partly filled(or incomplete) d-subshell. It has 3d-subshell full filled.
Transition metals show vacant d-orbitals but Zn metal has completely filled d-orbitals.
∴ Zn is not regarded as the transition element.
