Physics - Magnetism Question with Solution | TestHub

The magnetic moment of the ground state of an atom whose open sub-shell is half filled with $\mathrm{n}$ electrons is given by $\mu =\sqrt{\mathrm{n}(\mathrm{n}+2)}\cdot {\mu }_{\mathrm{B}}$ where ${\mu }_{\mathrm{B}}$ is the gyromagnetic moment of the atom. Here, $\mathrm{n}=5$ $\therefore \mu =\sqrt{5(5+2)}\cdot {\mu }_{\mathrm{B}}=\sqrt{35}{\mu }_{\mathrm{B}}$
