magnetic properties

Question

Paramagnetism in transition metal ions is due to:

RankGuru · Accepted Answer

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