Question
Gouy Balance 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 off On sample Paramagnetic Diamagnetic This animation is for interest only It is not needed to answer the question. O Be Al NeExplanation / Answer
O: [He]2s22p4: It has two unpaired electrons in th 2p orbital, hence it is paramagnetic
Be: [He]2s2: All electrons are paired, therefore it is diamagnetic
Al: [Ne]3s23p1: It has one unpaired electron in th 3p orbital, hence it is paramagnetic
Ne: [He]2s22p6: All electrons are paired, therefore it is diamagnetic
