Question

Why $\mathrm{Zn}$is not a Transition Metal?

Answer 1

Transition metals:

• Transition metals are those metals that are partially filled with d-orbitals.
• $\mathrm{Zinc}\left(\mathrm{Zn}\right)$ is not considered as the transition metal because it has completely filled with the d-orbitals.
• The electronic configuration of Zinc is as:
• $\mathrm{Zn}=1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}4{\mathrm{s}}^{2}3{\mathrm{d}}^{10}$

Thus, $\mathrm{Zn}$ is not the transition metal as it doesn't have any vacant 3d orbital.
