The octet rule<span> is a chemical </span>rule<span> that observes that atoms of main group elements combine in such a way that each atom has eight electrons in its valence shell giving it the same electronic configuration as a noble gas. good luck! hope this helps!</span>
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule, making it useful for the main group elements (elements not in the transition metal or inner-transition metal blocks); an octet in these atoms corresponds to an electron configurations ending with s2p6.
