Nov 11, 2014  · Re: Paramagnetic vs Diamagnetic. Yes, the MO diagram for Z<8 is used because one of the two atoms is Z<8. CO+ is paramagnetic because it has an odd number of electrons. A molecule that has an odd number of electrons is always paramagnetic because there’s no way to pair all of the electrons. That’s why when doing this problem,
