WebHydrogen and helium are special cases that do not follow the octet rule but the duplet rule. They contain an s s orbital but no p p orbitals. They are stable in a duplet state instead of an octet state. Duplet rule: Hydrogen and helium have filled their outermost shell and reached a stable configuration when they have two electrons. WebAug 11, 2024 · The p- and s-block elements heed the octet rule except for helium, hydrogen, and lithium (Li). Metals such as sodium or magnesium also obey the octet rule. Some other rules, such as the duplet rule or rule of two and 18-electron rules, are followed by other elements.
