A Gouy balance is used to determine the magnetic susceptibility of a substance. A strong electromagnet is placed next to the sample, which is on a balance. If the sample is paramagnetic, the mass reading of the balance will increase when the field is switched on. Based on their electron configurations, predict whether these elements are paramagnetic or diamagnetic.

Paramagnetic:
?
Diagmagnetic:
?

Elements:
Ar Be C P

    Write their electron configuration, then determine if they have unpaired electrons.
    13Al = 1s2 2s2 2p6 3s2 2p1. Yes, it has 1 unpaired electron so it is paramagnetic.

  • Chemistry -

    Is all the elements diamagnetic?

  • Chemistry -

    No. All of the elements are not dimagnetic. The Al I wrote is paramagnetic.

  • Chemistry -

    There is no Al. Only Ar. The elements are Ar, Be, C, P.

  • Chemistry -

    I know that. I wrote Al, thinking that if you knew how to do Al you would know how to do the others. I answered all of these at your other post.
