प्रश्न
Give a reason for the following:
Cu+2 salts are paramagnetic, while Cu+ salts are diamagnetic.
उत्तर
The electronic configurations of Cu2+ and Cu+ are [Ar] 3d9 4s0 and [Ar] 3d10 4s0, respectively. Cu2+ has one unpaired electron, making it paramagnetic, whereas Cu+ has no unpaired electrons, making it diamagnetic.
