What is an ionic bond?

In ionic bond there is the formation of ions due to transfer of electrons from one atom to the other. Normally, at this link, there is an element that tends to yield electrons (metal-cation), and one that tends to receive electrons (not metal-anion).

Note: the Ionic bond is the only in the transfer of electrons.

Ionic bonds are when atoms lose or gain electrons so that both elements now have a full outer shell. Ionic bonds form between metals and nonmetals.
