Pairing of electrons in various orbitals of a suborbit takes places only after each orbital is half-filled. No two electrons in an atom can have the same set of quantum number. While writing the following electronic configuration of Fe some rules have been violated : I : Aufbau's rule, II : Hund's rule III : Pauli's exclusion principle
