Sc (Z = 21) is a transition element but Zinc (z = 30) is not because

Answer»

both `Sc^(3+)` and `Zn^(2+)` ions are colourless and form white compounds,
in case of Sc, 3d orbital are partially filled but in Zn these are completely filled
ast electron as assumed to be added to 4s level in case of zinc
both Sc and Zn do not EXHIBIT variable OXIDATION states

Solution :in case of Sc, 3d orbital are partially filled but in Zn these are completely filled
