Vedclass · Answer

(C) The spin-only magnetic moment is given by $\mu = \sqrt{n(n+2)} 	ext{ BM}$, where $n$ is the number of unpaired electrons.$(A)$ $Ti^{3+}$ $(Z=22)$: $[Ar] 3d^1$, $n=1$.$(B)$ $Cr^{3+}$ $(Z=24)$: $[Ar] 3d^3$, $n=3$.$(C)$ $Mn^{2+}$ $(Z=25)$: $[Ar] 3d^5$, $n=5$.$(D)$ $Fe^{3+}$ $(Z=26)$: $[Ar] 3d^5$, $n=5$.$(E)$ $Sc^{3+}$ $(Z=21)$: $[Ar] 3d^0$, $n=0$.Since $Mn^{2+}$ and $Fe^{3+}$ both have $n=5$ unpaired electrons, they exhibit the same spin-only magnetic moment. Thus, the correct option is $(C)$.

Which of the following ions exhibit the same value of spin-only magnetic moment? $(A)$ $Ti^{3+}$, $(B)$ $Cr^{3+}$, $(C)$ $Mn^{2+}$, $(D)$ $Fe^{3+}$, $(E)$ $Sc^{3+}$. Choose the most appropriate answer from the options given below.
