How do we write spin multiplicity for Mn(2+), Mn(7+)?

Armand Wong Sr.  Follow

Spin multiplicity = $2S+1$, where $S$ is the total spin angular momentum. Now $S = \frac{n}{2}$ where $n$ represents total number of unpaired electrons. So now we can write spin multiplicity = $n+1$.

Now coming to your question,

  • $\ce{Mn}$ has 5 unpaired electrons in it. Therefore, its spin multiplicity $(S) = 5+1 = 6$.
  • Similarly, $\ce{Mn^{2+}}$ has 5 unpaired elections in it. Therefore, its spin multiplicity $(S) = 5+1=6$.
  • $\ce{Mn^{7+}}$ has zero number of unpaired electrons. Therefore, its spin multiplicity $(S) = 0+1=1$.
