Fall 2014 Quiz 2 prep #9

Postby Michael Lonsway 3O » Sun Nov 06, 2016 2:24 pm

This problem asks which statement is false and the answer was: Atoms or molecules with an even number of electrons are diamagnetic. I was wondering what this was false since I thought that atoms/molecules with an odd amount of electrons were paramagnetic while the ones with event electrons were diamagnetic. What would the exception for this be?

Atoms that are paramagnetic have unpaired electrons, and atoms that are diamagnetic have no unpaired electrons. I think it would be possible to have an atom with an even number of electrons be paramagnetic when you have an atom with 4 electrons in the p orbital; 2 electrons would be unpaired, making it paramagnetic. If we were looking at a molecule, the last 2 electrons the atoms were sharing may be split between a pi px and pi py orbital, making it paramagnetic as well. Hope this helps!
