It doesn't act like one because it usually ionizes to the +3 oxidation state, where there are no valence electrons. Usually yttrium, lanthanum, and actinium in the same family are not considered transition metals either.
Most other transition metals ionize such that there are still electrons left in the d orbitals.

the most effortless oxidation state of scandium in is +3. Scandium chemically resembles yttrium and the uncommon earth metals more effective than it resembles aluminium or titanium. as a effect scandium is often considered because the scandium oxide, Sc2O3, and as scandium chloride, ScCl3. the region will tell u all u want to understand bout this metal

Are you sure you didn't mean to ask why is scandium the very first transition metal to appear in the periodic table?

who says that Sc is not transition meta! It is a tran. metal w/ atomic # of 21 ( 1s1, 2s2, 2p6, 3s2, 3p6,4s2, 3d1). since it has 3d1, that is the properties of tran.metals.

because it has valance electron in S sub orbit all the other orbits are full and stable
