Name the following ionic binary compounds. Remember these steps. 1 - Use a periodic table to find the oxidation number for each element. 2 - Write the symbol for the element that has the positive charge. This would be your metal. Write the symbol for the element that has the negative charge. This would be your nonmetal. 3 - Perform a swap by taking the charge on one ion and using that as your subscript for the other ion. Don't forget to remove the sign (+ or -) when writing the subscripts, as they are not allowed in chemical formulas. 4 - When naming a new compound, the cation name goes first. The anion name gets an -ide ending and goes second.
