"When a bond is formed by the complete transference of a certain number of electrons from one atom to another atom, so that both acquire stable electronic configuration".
For example,
Consider the combination of sodium and chlorine to form sodium chloride. Sodium (2,8,1) possesses one surplus electron, by loosing it sodium changes into sodium ion attaining stable electronic configuration of inert gas Neon (2,8). On the other hand chlorine (2,8,7) needs one electron, and by gaining chlorine changes into chloride ion to attain stable electronic configuration of inert gas Argon (2,8,8).
