WebbIonic bonds form when one atom has a much higher electronegativity than another. This causes the electronegative atom to pull electrons from the less electronegative atom, forming ions that stick to one another via electrostatic forces. Hydrogen doesn't form ionic bonds because it has a very average electronegativity of 2.1.
