Which of the following electronic configuration would be associated with the highest magnetic moment?
1 \([A r] 3 \mathrm{~d}^{7}\)
2 \([\operatorname{Ar}] 3 \mathrm{~d}^{6}\)
3 \([\mathrm{Ar}] 3 \mathrm{~d}^{8}\)
4 \([\operatorname{Ar}] 3 \mathrm{~d}^{3}\)
Explanation:
Magnetic moment \((\mu)=\sqrt{\mathrm{n}(\mathrm{n}+2)}\) where ' \(n\) ' is no. of unpaired \(e^{-}\). More are the no. of unpaired electrons, more is the magnetic moment (spin only)

The magnetic moment of a transition metal ion is \(\mathrm{\sqrt{15}}\) B.M. Therefore the number of unpaired electrons present in it is
1 4
2 1
3 2
4 3
Explanation:
Magnetic moment \(\mathrm{=\sqrt{n(n+2)}}\) B.M. Where, \(\mathrm{\mathrm{n}=}\) no.of unpaired electrons Given, \(\mathrm{\mu=\sqrt{15}}\) \(\rm{\therefore \sqrt{15}=\sqrt{n(n+2)} \Rightarrow 15=\mathrm{n}(\mathrm{n}+2)}\) This is possible only when \(\mathrm{\mathrm{n}=3}\).
