Question

Calculate the magnetic moment of a divalent ion,M+2 in aqueous solution, if the atomic number is 25

Answer 1

The divalent ion in aqueous solution with atomic number 25 will be having a d⁵ configuration
i.e. it will be having 5 unpaired electrons
Magnetic moment can be calculated as follows:
$$\begin{gathered} \mu =\sqrt{5(5+2)} \\ =5.92BM \end{gathered}$$
