In other words, the element symbol for the metal is written before the symbol for the nonmetal. Recognizing Compounds With Ionic Bonds You can recognize ionic compounds because they consist of a metal bonded to a nonmetal. Ionic bonds form between two atoms that have different electronegativity values. Because the ability to attract electrons is so different between the atoms, it's like one atom donates its electron to the other atom in the chemical bond. More Bonding Examples In addition to ionic bond examples, it may be helpful to know examples of compounds that contain covalent bonds and also compounds that contain both ionic and covalent chemical bonds.
