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.
