Question

How is the magnetic moment of a magnetic species related to the number of unpaired electrons?

Answer 1

1. The magnetic moment of a magnetic species depends on the number of unpaired electrons it has.
2. The magnetic moment (μ) due to spin only is given by the formula: `mu_s = sqrt(n(n + 2))BM` (Bohr Magneton) where (n) is the number of unpaired electrons.
3. More unpaired electrons mean a higher magnetic moment and stronger paramagnetism.
4. When electrons are paired, their magnetic effects cancel, resulting in zero net magnetic moment and diamagnetism.
