    Which of the two is paramagnetic: V (IV) or V (V) and why?

    Answer:

                    Electronic configuration of V (Z = 23) is [Ar]18 3d3 4s2 \[\therefore \] V (IV) is \[{{[Ar]}^{18}}\,3{{d}^{1}}\]  and V (V) is \[{{[Ar]}^{18}}3{{d}^{0}}\] As V (IV) has one unpaired electron, therefore, it is paramagnetic.
