The illustration depicts the formation of an ionic chemical bond between sodium and chlorine atoms. The result of this bonding is a chemical compound that is stable because the

• transferred electron provides chlorine with a full outer energy level.

• shared electron provides both elements with a full outer energy level.

• shared electron provides provides sodium with a full outer energy level.

• transferred electron provides both elements with a full outer energy level.
