One method of experimentally determining whether a species is paramagnetic is to weigh it in an instrument called a magnetic susceptibility balance. This is a balance with a strong electromagnet placed next to the sample holder. If the species is paramagnetic, the mass reading of the balance will increase when the field is switched on. Classify these species as paramagnetic or diamagnetic. Paramagnetic Diamagnetic Answer Bank Which species will have the strongest mass shift on a magnetic susceptibility balance? CO NO O 2 F 2
