The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spin only magnetic moment value of

\mathrm{Cr}^{3+}

ion (Atomic number : Cr = 24) is ____.

Solution:

µ , spin angular momentum =

\sqrt{(n)n+2}.

B.M. Electronic configuration of

\mathrm{Cr}^{3+} = [\mathrm{Ar}]\ 3d^3

Number of unpaired electrons = 3

\mu = \sqrt{3 \times 5} = \sqrt{15} = 3.87\ \mathrm{B.M.}
