Although $Cr^{3+}$ and $Co^{2+}$ ions have the same number of unpaired electrons the magnetic moment of $Cr^{3+}$ is 3.87 B.M. and that of $Co^{2+}$ is 4.87 B.M. Why?

Answers (1)

Unlike $Cr^{3+}$ , $Co^{2+}$ has a symmetrical electronic configuration, due to which the magnetic moment is higher for Cobalt ion.
