So, once again, to recap an Ionic bond is a bond between a count ion and an anion. And what that basically means that neutral charges or neutral atoms will not be able to form ionic bonds. In order to form an ionic bond, you have to have a positive atom and a negative atom. And the only way ionic bonds form is if you mix atoms from this side, from the left side of the periodic table with atoms on the right side of the periodic table. So one last important thing that I'd like to mention. So let's look at the electron configuration of these two atoms.
