Bonding and the Outer Shell Atoms with incomplete shells react with others in a way that allows it to complete the outer shell. Atoms react to give up, receive, or share electrons to produce a completed outer shell. Atoms with a complete outer shell do not react with other atoms. The outer shell is called the valence shell. Its electrons are valence electrons. Chemical bonds form when two or more atoms react to fill their outer shells with electrons. A compound is two or more elements joined together by chemical bonds. Ionic Bonding Atoms with unfilled outer shells may transfer electrons from one to another. The transfer enables the atoms to have complete outer shells. A sodium atom (Na) and a chlorine atom (Cl) are shown below. A single circle represents the nucleus (protons and neutrons) of the atoms. Dots represent the electrons. The sodium atom has a total of 11 electrons and one electron in its outer shell. Chlorine has a total of 17 electrons with seven in its outer shell. From this, we can see that the atomic number (number of protons) of sodium is 11 because the
