1 Answer. Problem: The ground-state electron configuration of a Mn2+ ion is 1s22s22p63s23p63d5. Therefore, if there are 4 electrons, or 9 electrons in the d orbital, it will move one electron from the s orbital below it to fill the extra space. paramagnetic with three unpaired electrons. Hund's rule states that the most stable arrangement of electrons (for a ground state electron configuration) has the maximum number of unpaired electrons, all with the same spin. We now shift to the 4s orbital where we place the remaining two electrons. Therefore, one of the 4s2 electrons jumps to the 3d5 so that it is half-filled (see video below).
