Whether a molecule is paramagnetic or not is only explained using molecular orbital theory. Sparks55 3F Posts: 18 Joined: Fri Sep 25, 2015 10:00 am. The reason that it is paramagnetic is because the oxygen molecule has two unpaired electrons. Gaseous oxygen is paramagnetic also but is moving too fast to be affected by the magnets. https://en.wikipedia.org/wiki/Diamagnetism Ferromagnetism Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. An atom is considered to be paramagnetic when it has unpaired electrons present in the orbitals whereas diamagnetic atoms or compounds do not have unpaired electrons. Units . Thus those two species should also be paramagnetic. • among the following reactions find those that are redox reactions? A O22- ion is: a. paramagnetic.
