A molecule or compound is made when two or more atoms form a chemical bond, linking them together. In an ionic bond, the atoms are bound together by the attraction between oppositely charged ions. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt. It is a reaction between a metal and a non metal. Ionic compounds dissolve easily in water and other polar solvents. In ionic bonding, valence electrons are taken from the less electronegative atom and the more electronegative atom receives it.
Here is a helpful video to show case ionic bonding:
