Ionic Coupling Ionic Coupling The ionic combination magnesium fluoride, for example, is made up of magnesium and fluorine from Groups 2 and 17. Magnesium donates a one-one electron to each fluorine atom to form an ionic bond. An atom of fluorine will be more stable it it "gets" one more electron to complete it's outer shell. ionic BeF2 is covalent, while LiF is ionic. Therefore, krypton and lithium are most likely to form an ionic bond. Nutritional, Physicochemical, Microstructural, Rheological, and Organoleptical Characteristics of Ice Cream Incorporating.
