WebNot all elements follow the octet rule. H, He, Li, and Be never follow the Octet Rule. Boron usually does not follow the octet rule, though it sometimes does. Other elements, such as S and P, sometimes do not follow the octet rule. So, the octet rule is not a strict law of science that is always followed.
