How is it possible for two different ionic compounds to contain. the same elements?
Because alkali metals, alkaline earth metals, and aluminum form ions with positive charges equal to the group number. Oxidation states are important. As an example, Iron can exist is a number of oxidation states. Oxygen prefers to be minus 2. However, just these two elements can produce FeO Fe2O3 Fe3O4 So 3 different (never mind 2!!) ionic compounds from the same elements
