$Sc\, (Z = 21)$ is a transition element but $Zn\, (Z = 30)$ is not because
both $Sc^{3+}$ and $Zn^{2+}$ ions are colourless and form white compounds.
in case of $Sc, 3d$ orbitals are partially filled but in $Zn$ these are filled.
last electron is assumed to be added to $4s$ level in case of $Zn.$
both $Sc$ and $Zn$ do not exhibit variable oxidation states.
