Here are some examples for you: Zn 2+ is zinc. S 2- is sulfide. Put them together for zinc sulfide (ZnS). Here's another: K2O is potassium oxide Naming Ionic Compounds Containing Transition Metals A transition metal is a metal that can use the inner shell before using the outer shell to bond. These are the elements in the middle of the periodic table - things like zinc, iron and copper. Naming polyatomic ionic compounds that have transition metals in them is also fairly easy. It follows the same naming rules as the simple binary compounds, but with an extra rule added in. So, you still name the cation first, followed by the anion with the suffix -ide added to the end of it. The new rule is that transition metals form more than one ion, so this has to be accounted for in the naming. We do this by using Roman numerals to denote which ion it is. The Roman numeral will equal the charge on the ion. For instance, Fe 2+ is iron (II). Fe 3+ is iron (III). When compounds are formed with these metals, the different ions still have to be accounted for. If I told you the compound was iron chloride, that wouldn't give you the full story. You wouldn't know if it was iron (II) or iron (III), which means you don't know how many chlorine atoms are in the compound to bond with the iron, since two chlorines would be needed for iron (II) and three for iron (III). If I instead told you that the compound was iron (II) chloride, you would know that it was Fe 2+ in there, which means you have two chlorine atoms bonding with it. The formula would be FeCl2. If I said it was iron (III) chloride, the formula would be FeCl3. Naming Polyatomic Ionic Compounds A polyatomic ionic compound is a compound made up of a polyatomic ion, which is two or more atoms bonded together, and a metal. Naming polyatomic ions is harder, but doable. First, name the cation, which is just the name of the element. Next, name the anion. This gets trickier. Notes Section: you must first figure out all of the ions and then put them together you must combine the a and d terms, and combine the c and b terms 64
