Sodium Chloride, NaCl. The classic case of ionic bonding, the sodium chloride molecule forms by the ionization of sodium and chlorine atoms and the attraction of the resulting ions. An atom of sodium has one 3s electron outside a closed shell, and it takes only 5.14 electron volts of energy to remove that electron. The chlorine lacks one electron to fill a shell, and releases 3.62 eV when it acquires that electron (it's electron affinity is 3.62 eV).
Na is a metal and Cl is a non metal. Ionic bonds are between a metal and a non metal. Therefore, Sodium Chloride (NaCl) is an ionic co â¦ mpound.
