The elements that are diamagnetic in the first transition series has to be identified. Concept Introduction: Diamagnetic: When atoms or ions with all electrons are paired their magnetic field effectively cancels each other. Substances with paired electrons are called diamagnetic. They are weakly repelled by magnetic fields. Paramagnetic: Atoms or ions with unpaired electrons are attracted to magnetic field. Substances with unpaired electrons are called paramagnetic.
