Example: If a simple ionic compound is made of these two ions, what is its formula? In the final formula, don't write the charges on the ions!
88 WRITING AN IONIC FORMULA - if you know the ions that make up a compound, all you need to do is find the smallest ratio of cation to anion the compound needs to have an overall charge of zero Example:
