Which of the following gaseous ions have the same no. of unpaired electrons in ground state?
a Co 2+ [...3d7]
b V 2+ [...3d3]
c Cr3+ [..3d3]
Just showing the electrons in the 3d subshells since those in front are fully filled. Anyway, all has got 3 unpaired e-. So is the answer a,b and c? Not sure 'bout this.
