Solution
Correct Answer:
Presence of unpaired d electrons
- Magnetic Moment: Every electron has a spin magnetic moment associated with its 'spin' around its own axis.
- Paired Electrons: In a pair, the two electrons have opposite spins, effectively cancelling each other's magnetic moments (Diamagnetism).
- Unpaired Electrons: When an orbital contains only one electron, its magnetic moment is not cancelled.
- Paramagnetism: Substances containing one or more unpaired electrons are attracted by a magnetic field and are termed paramagnetic.
- Source: In transition metals, these unpaired electrons are typically found in the d-subshell.
