Vedclass · Answer

(A) True: The magnetic moment of transition metal ions is due to both spin and orbital angular momentum of electrons.$(b)$ True: For $Mn^{2+}$ ($d^5$ configuration),the number of unpaired electrons $n = 5$. The spin-only magnetic moment is $\mu = \sqrt{n(n+2)} = \sqrt{5(5+2)} = \sqrt{35} \approx 5.92 \ BM$.$(c)$ False: Interstitial compounds are non-stoichiometric compounds formed when small atoms like $H, C, N$ are trapped inside the crystal lattice of transition metals. They are typically metallic in nature,not covalent.

Determine whether the following statements are True $(T)$ or False $(F)$:
$(a)$ The magnetic moment arises from the spin and orbital motion of electrons.
$(b)$ The magnetic moment of $Mn^{2+}$ is $5.92 \ BM$.
$(c)$ Interstitial compounds are covalent compounds.
