Answer Key / Explanation : (a,b,c) -

(a,b,c)

This is because  is a more stable half-filled configuration. Reasons for the stability of half-filled and fully filled orbitals are symmetry and exchange energy

For every value of  can be from  to  through 0

23 electrons have a spin of one type and 24 of the opposite type

The oxidation state of  in  is not  but
