Question

What are typical and non-typical transition elements?

Answer 1

Transition elements:

• The d-block elements or the elements of the group $3$ to $12$ in the Modern periodic table are called transition elements.
• Transition elements are usually metals.

Typical transition elements:

• The transition elements usually have partially filled d-orbitals such as $\mathrm{Fe}$, $\mathrm{Co}$, $\mathrm{Ni}$, etc. are called typical transition elements.

Non-typical transition elements:

• The elements present in the d-block that have completely filled d-orbitals are called non-typical transition elements.
• The non-typical transition elements are $\mathrm{Zn}$, $\mathrm{Cd}$ and $\mathrm{Hg}$.
