In ionic bonding, [|electrons] are completely transferred from one [|atom] to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form [|ions]. The oppositely charged ions are attracted to each other by electrostatic [|forces], which are the basis of the [|ionic bond]. For example, during the reaction of sodium with chlorine:

chlorine (on the right), ||
 * sodium (on the left) loses its one [|valence electron] to [[image:http://www.visionlearning.com/library/modules/mid55/Image/VLObject-2994-041102031104.jpg width="223" height="153" align="center" caption="Sodium&Chlorine-transfer"]]
