Examples of Ionic Bonds and Compounds

Here are examples of ionic bonds and ionic compounds: NaBr:Â  sodium bromideKBr: potassium bromideNaCl: sodium chlorideNaF: sodium fluorideKI: potassium iodideKCl: potassium chlorideCaCl2:Â  calcium chlorideK2O: potassium oxideMgO: magnesium oxide Note that ionic compounds are named with the cation or positively-charged atom written before the anion or negatively-charged atom. 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, its 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.
