Question

A Gouy balance is used to determine the magnetic susceptibility ofa 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 Diamagnetic Paramagnetic Na Si Са Ar Answer Bank

Answer 1

Ans ) a) Paramaguetie = Paramagnetism is a form of magnetism whereby some matveals que weakly extra acted by an extewnally applied magnetic field, and induced magnetic field in the applied magnetic feid b) Diamagnetism = s diamagnetic substance is one where atoms have no permanent magnetic wolé hole movement. When an external magnetic field was applied ito a diamagnetic scukutanck. wuah als bis muth or silver a wzak magnetic dipole namrent is introduced in the direction of heelte the applied field Diamagnetic, all whins here are paired. Solution 351 Na = [NeJ 3s', m cone unpaired e so, it is Para magnetic 45² © Cele = [A] 453, vi e are haired, so it į Diamagnetic ♡ Si = [Ne] 35? 3p² Tonto e are unhaised 80 it is Para magnetic As a [Ne ] 3² 3p6 [12/11/17 Ŕ are paired so it is Diamagnetic Thank you
