What is the "octet rule?" a.
The octet rule says that atoms are most stable when they have a full shell of electrons in the outermost shell
c.
The octet rule says that any atom can form a maximum of eight covalent bonds
b.
The octet rule states that the sum of all electrons in the lower subshells must equal eight
d.
None of the above

A

Explanation:

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 .
