Is $\mathrm{Zn}$ paramagnetic or diamagnetic?

Diamagnetic substances:

1. The diamagnetic materials all possess paired electrons, but none of them are valence electrons resulting in the lack of atomic dipoles in these materials. This occurs because the overall magnetic moment of the atom cancels out.
2. The diamagnetic substance and the magnet repel one another in the presence of the magnetic field.
3. Examples of diamagnetic materials include gold, copper, and nitrous oxide.
4. Temperature has no impact on materials that are diamagnetic
5. Zinc is an element with an atomic number$=30$ and its electronic configuration is$1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}3{\mathrm{d}}^{10}4{\mathrm{s}}^2$.
6. Since there are no unpaired electrons present in zinc's outermost orbital, it is diamagnetic in nature.

Therefore, Zinc is diamagnetic.
