These orbitals are part of different shells and sub-shells and are characterized by the three quantum numbers viz. n,l and ${m_l}$. Let us now take up the distribution of electrons in these shells and sub-shells. Such a distribution of electrons is called Electronic Configuration and is governed by three basic rules or principles.
