WebMar 28, 2024 · Exceptions. There are exceptions to the octet rule. Two Electrons. The main exception to the rule is hydrogen, which is at its lowest energy when it has two electrons in its valence shell. Helium (He) is similar in that it, too, only has room for two electrons in its only valence shell. Hydrogen and helium have only one electron shell. WebThe valence orbitals of hydrogen (and helium) have a principle quantum number of 1, and so there is only one orbital available, the 1s. Since each orbital can contain up to two electrons (of opposite spin), hydrogen can have 2 electrons in its Lewis Dot Structure.
