Scandium is a transition element. But Zinc is not. Why ?

Text Solution

Verified by Experts

Scandium has electronic configuration `[Ar]4s^(2)3d^(1)`.
Zinc has electronic configuration `[Ar]4s^(2)3d^(10)`
Scandium has one unpaired d-electron where as Zinc has zero unpaired d-electrons so Scandium is transition element but Zinc is not.
