The #"octet rule"#, which is more a rule of thumb than an actual chemical principle.


Main-group elements tend to form compounds in which the participating atoms are surrounded by #"8 electrons"#. There are many exceptions to the rule, but often we can rationalize the chemistry of the exceptions in terms of filling the valence shell of the participating atoms with 8 electrons.
