The result is that chlorine will very often form a compound in which it has eight electrons in its outer shell (a complete octet), as in Cl−.

19 сент. 2012 г. · Atoms that have eight electrons in their outer shell are extremely stable. It can't be because both the s and the p orbitals are full.

29 янв. 2023 г. · The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell.

An atom is said to be more stable when it has a complete outer electron shell, which typically equates to 8 electrons. This is what the octet rule says.
