This is a rule that says that atoms tend to combine to complete electrons to 8. And that means that the two atoms tend to combine to complete a shell to 8 electrons. Hope i helped. Have a nice day
The octet rule is that atoms must have 8 valence electrons to have an octet. Usually, when atoms have an octet, they tend not to bond with any other atoms because they are already stable and do not need to bond anymore.
