The exclusion principle, proposed by Pauli, states that no two electrons in an atom can have the same set of quantum numbers. This leads to an arrangement of electrons in atoms such that no more than two electrons occupy any given energy level or orbital, which is essential for the stability and chemical reactivity of atoms.
