Question

Knowing the number of unpaired electrons, how would you calculate the magnetic moment of a transition metal ion?

Answer 1

1. Identify the number of unpaired electrons (n) in the transition metal ion from its electronic configuration.
2. Use the formula for spin-only magnetic moment:
   μ_s = `sqrt(n(n+2))` Bohr magnetons (BM)
3. Substitute the value of n (unpaired electrons) into this formula.
4. Calculate (μ_s), which gives the magnetic moment in BM, reflecting the ion’s paramagnetism.
