State octet rule

The octet rule is a chemical principle that states that atoms tend to lose, gain, or share electrons in order to achieve a stable configuration with 8 electrons in their outermost shell (except for hydrogen and helium, which are stable with 2 electrons in their outer shell). This stable configuration is known as the "octet" or "noble gas" configuration, which is typically seen in the noble gases such as helium, neon, and argon. By following the octet rule, atoms can achieve a more stable and low-energy state.
