    Answer:

    The octet rule means that atoms need a total of 8 valence electrons to fill their valence shell. Hydrogen only needs two to fill its valence shell.

    Explanation:

    All atoms except for hydrogen can hold a total of 8 valence electrons in their outer energy levels (2 in the s level, 6 in the p level). Hydrogen only has two electrons total, so it does not require more than the s level and two electrons to have a full valence.

    1. 8 (oct means that eight, good way to remember this!)
    2. hydrogen has ONE valence electron!

    hope this helps 🙂
