why zinc salts are diamagnetic
Answers
The re are no unpaired electrons in sodium chloride and sodium chloride is diamagnetic. Manganese(II) sulfate monohydrate is strongly attracted by the magnet, which shows that it is paramagnetic. ... This compound is not as strongly paramagnetic as the manganese(II) sulfate. Iron(II) ions have four unpaired electrons.
Zn as well as its ion Zn2+ arr diamagnetic in nature because
For zinc the electronic configuration is 3d10 4s2 with a vacant p orbital .Hence all the electrons present are paired up. So if we take an electron with positive magnetic spin, we will have another electron paired with it which will have opposite spin. Hence the effect of all the electrons is cancelled out by their pairing partner.
In the case of Zn2+ion the configuration is 3d10 and hence the same reason is valid here also.
Hope it would help.
