Of the "ferric ion..........?"

Explanation:

For "iron", Z=26, and thus for elemental iron we have to distribute 26 electrons by the aufbau scheme, and for Fe^(3+), we must distribute 23 electrons..................And so:

1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(5).

Note that a neutral iron atom has a configuration of.......

1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^(6) (26 electrons as required.) However, upon oxidation, the 4s electrons are conceived to be removed FIRST, and this is typical for transition metal ions.

Would Fe(III) complexes be paramagnetic? Why or why not........?
