An ionic bond forms between sodium and chlorine when the sodium atoms donate elections

Explanation;Ionic bond is a type of bonds that results from transfers of electrons from one atom to another.  This types of bond is formed between metals and non metals.Metals lose electrons to form cations (positively charged ion) and non metals gain electrons forming anions, negatively charged ion. In this case, sodium donates and electron to chlorine atom, thus they both achieve a stable electronic configuration forming ions.
