(D) The magnetic moment $\mu$ is given by the formula $\mu = \sqrt{n(n + 2)} \ BM$,where $n$ is the number of unpaired electrons.Given $\mu = 2.83 \ BM$.$2.83 = \sqrt{n(n + 2)}$Squaring both sides,we get $8 = n(n + 2)$.$n^2 + 2n - 8 = 0$.Solving the quadratic equation: $(n + 4)(n - 2) = 0$.Since $n$ must be positive,$n = 2$.
