Pure ionic bondingcannot exist: all ionic compounds have some degree of covalent bonding. Examples of ionic bondslithium fluoride lithium chloride lithium bromide sodium fluoride sodium chloride sodium bromide potassium fluoride " Valence electrons Predict the composition of an ionic compound from its chemical formula.VOCABULARY / CONCEPTS- electron dot diagram Stable electron configuration Relate the properties of ionic compounds to the structure of crystal lattices.VOCABULARY / CONCEPTS- electron dot diagram Stable electron configuration
