    The octet rule is a very important prinicple in chemistry.

    The octed rule states that the atoms trend to win, lose or share electrons to acquire a complete set of 8 electrons in the outer shell.

    For example Sodium has 1 valence electron and it will be happy to lose that electron to stay with 8 electrons in the outer shell.

    Chlorine has 7 valence electrons, so it will be happy to accept 1 more electron to have 8 electrons in the outer shell.

    When sodium and chlorine bond, they share their valence electrons and each atom is surrounded by 8 electrons, which is a stable configuration. That is how the sodium chloride is formed.
