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.

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.
