Homework Help: Paramagnetism of negative O2 ion

  1. Jun 3, 2014 #1
    O2 has two unpaired electrons, therefore it's quite strong paramagnetism.

    But what about (O2)-, the negatively charged O2 ion?

    Am I right in assuming that due to the additional electron one unpaired electron will get together with it, so that overall it should still be paramagnetic, but not so strong anymore?

    Or does the additional electron behave somehow differently and doesn't change the paramagnetism, or even increases it???
    It couldn't find much info about the behavior of ions in this relation, so I would be grateful for any explanation in this direction.

    Thanks

    OK, in the meantime I did find out (after a thorough search on the net), that (O2)- is really paramagnetic, and that it really just has one unpaired electron. So it is paramagnetic, but less than O2. This is what I guessed, but now I know...
