The highest magnetic moment is shown by which transition metal ion with the given outermost electronic configuration?

3d⁵

Magnetic moment is given by,

υ = \(\sqrt {n(n+2) }\)

More the number of unpaired electrons, higher will be the magnetic moment.

In 3d⁵ configuration, no of unpaired electrons = 5

υ = \(\sqrt {5(5+2) }\) = \(\sqrt {5 × 7 }\) = \(\sqrt {35 }\) = 5.91 B.M
