For questions 5-8, write names for the binary salts of representative elements. These are ionic compounds in which the metal ion has only one observed charge. Therefore, it is not necessary to designate the charge of the metal ion. The expected charges of the ions, and the need to have the formula in lowest terms, means that no Greek prefixes are necessary to indicate the number of ions in the formula. 5. CaF2 6. MgaN2 7.
