Scandium element atomic number=21
Scandium belongs to D block in which elements mostly exhibit variable oxidation state [valency.]
Electronic Configuration:
1s2 2s2 2p6 3s2 3p6 4s2 3d1
Valence electrons are 3
Maximum valency it can exhibit is 3
Valency :it can loose 2 electron from 4s and shows +2 oxidation state.
if it losses 1 electron from 3d then it shows +3 oxidation state.

HEY!!
The atomic number of scandium is 21. It is a transition metal and shows a valency of 3. Transition metals are basically the metals that occur in the middle of the periodic table and involve the filling of d-orbitals. These elements are known for showing variable valencies.
