Study Notes

Quantum Blocks and Element Classification

The p-block is named after the azimuthal quantum number (l=1) associated with the angular momentum of electrons.
The d-block corresponds to the transition metals, characterized by partially filled d-orbitals and common properties such as high conductivity and malleability.
The s-block is primarily considered as containing the main-group elements, which include groups 1 and 2 (alkali and alkaline earth metals) and helium, emphasizing their principal role in chemical reactions.
The term "periodic classification" was first introduced by Charles Janet, who categorized elements based on their atomic orbitals, paving the way for modern periodic table designs.
The f-block is associated with the inner transition metals (lanthanides and actinides), distinguished by their filling of f-orbitals and often noted for their complex electron configurations and unique properties.
