Answer
By the attraction between atomic particles of opposite charge
Explanation
An ionic bond is created by the attraction between atomic particles of opposite charge because when the charges are unlike they attract and in this type of attraction there is a complete transfer of charges. In the ionic bond complete transfer of charges takes place. Ionic bonds are formed between elements which have electronegativity changes greater than 1.4 or less than that. It is formed by a combination of cation and anion.
