A2.4 Magnetic Properties of Metal Compounds
- Paramagnetism: is a property of a substance which has unpaired electrons in its atomic structure allowing it to be drawn into a magnetic field.
- Diamagnetism: is a property of a substance with paired electrons. It will be repelled by a magnetic field. This is a much weaker effect than paramagnetism therefore paramagnetism will always dominate.
- d-block elements (transition metals) exhibit paramagnetism most strongly because their ions often have several unpaired electrons.
