Predicting lonic Compound Formulas Activity Ionic compounds are compounds composed of two substances which have a preferred ionic charge. The number of each type of compound must be balanced so that the ionic charge of the combination is zero, and the positive and negative charges balance. For each of the compounds below, you must interpret the name of the ionic compound using the naming rules to decide what elements or polyatomic groups make up the compound. Using the information on...
