Hello!!
for any element to be considered as transition element it must contain unfilled d orbital, zinc is definitely present with transition element but Zinc is not consider as a transition metal because its compounds or ions (Zn2+) contain a full filled d-orbital or sub shell and are unstable.
Thanks

Dear Aspirant
Zinc is not consider as a transition metal because its compounds or ions (Zn2+) contain a full filled d-orbital or sub shell and are unstable. Moreover it have only one ion which is the (Zn2+).
OR
The electron configuration of zinc is [Ar]4s 2 3d 10 . The only oxidative state which zinc has is Zn 2+ in which its configuration is [Ar] (4s 0) 3d 10 , as the 4s sub-level empties first. The definition of a transition metal is that it must have an incomplete d sub-level in one or more of is oxidation states. As zinc has a complete d sub level at all oxidative states it can't be considered a transition metal.
Thanks
All the very best
