- Which one of the following statements is incorrect, or are they all correct? In a Lewis structure, all valence electrons on the component atoms must be used – in bonds or lone pairs. The octet rule applies rigorously to C, N, O, and F in Lewis structures of common stable molecules H (Hydrogen) does not follow the octet rule because it cannot place more than 2 electrons into its valence shell. As central atoms (not in terminal positions), atoms such as P, S, and Cl may exceed an octet of electrons.
