Is Fe Diamagnetic?

Yes, iron (Fe) is generally considered **paramagnetic**, not diamagnetic.

### Explanation:

1. **Diamagnetic vs Paramagnetic**:
- **Diamagnetic** substances are those where all electrons are paired, and the substance is repelled by a magnetic field.
- **Paramagnetic** substances have unpaired electrons and are attracted to a magnetic field.

2. **Electronic Configuration of Iron (Fe)**:
- Iron has an atomic number of 26.
- Its electronic configuration is:
\(1s^2 2s^2 2p^6 3s^2 3p^6 3d^6 4s^2\).

3. **Unpaired Electrons**:
- In the 3d orbital, there are 6 electrons.
- Thus, **4 unpaired electrons** exist in the 3d subshell.

4. **Magnetic Properties**:
- Due to the presence of these unpaired electrons, iron exhibits paramagnetic behavior.

Therefore, iron is paramagnetic because of its unpaired electrons, and not diamagnetic.
