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).
NaI or Sodium Iodide is an ionic bond because sodium loses its electron which is gained by Iodine and both have a complete outer shell. This is a complete transfer of electro â¦ ns hence an ionic bond.
