Unformatted text preview: not all paired. The electrons add to the five different orbitals within the 3d orbital set one at a time and are thus not all paired. (NOTICE that even though Fe has an even number of electrons, that does not mean that all the electrons are paired!) Ti 2+ has a similar configuration in that the two 4s electrons are lost but the two 3d electrons occupy different 3d orbitals. Ar is a diamagnetic species since its valence shell is filled and all of its electrons are paired. S is not diamagnetic because it has four 3p electrons which are spread out among the three 3p levels, leaving two electrons unpaired....
