The ‘spin-only’ formula, µ = √n(n+2), helps calculate magnetic moments based on the number of unpaired electrons. Experimental data for first-row transition metal ions, mainly in hydrated forms, align with these calculations.

The magnetic moment increases with the number of unpaired electrons, making it a useful indicator of unpaired electrons in atoms, molecules, or ions. The observed magnetic moment correlates with the number of unpaired electrons.

The magnetic moment for compounds with unpaired electrons is calculated using the ‘spin-only’ formula: µ = √n(n+2), where n is the number of unpaired electrons. This formula, based on the number of unpaired electrons, helps determine the magnetic moment in ...

Paramagnetism in transition metal ions results from the presence of unpaired electrons, each carrying a magnetic moment associated with spin and orbital angular momentum. In compounds of the first series, the contribution of orbital angular momentum is effectively quenched.

Diamagnetic substances are repelled, while paramagnetic substances are attracted by an applied magnetic field. Ferromagnetism, an extreme form of paramagnetism, is characterized by very strong attraction to the magnetic field.
