Thank for that info jeff...
Naming Ionic Compounds- usually composed of a metal and a nonmetal.
1. The name of the cation is written first. Its name is as is (how it is written in the periodic table). For NaCl, you write sodium first. For CaBr2, you write calcium first.
2. The name of the anion is written next. The names of monatomic anions (anions made up of only one element) end with -ide. For NaCl, the name is sodium chloride. FOr CaBr2, the name is calcium bromide. More examples of monatomic anions with -ide ending are fluoride, iodide, sulfide, oxide, nitride, phosphide, carbide.....
3. For polyatomic anions (anions made up of more than one kind of element ), their names are unchanged. For CaSO4, the name is calcium sulfate. NaNO3 is sodium nitride. KOH is potassium hydroxide. Examples of polyatomic anions are SO4-2(sulfate), SO3-2(sulfite), NO3-(nitrate), NO2-(nitrite), OH-)hydroxide), etc. Unfortunately, the only technique on coming up with the names of the polyatomic anions easily is to be familiar with their names.
4. For cations with more than one oxidation states (usually transition metals), their oxidation states are specified in the names. They are represented by their equivalent roman numeral and enclosed in a parenthesis. Examples of metals with more than one oxidation states are Fe, Cu, Pb, etc. The name of FeCl3 is iron(III) chloride. Fe has an oxidation state of +3 and Cl has -1. The name of CuSO4 is copper(II) sulfate. Copper has an oxidation state of +2 and sulfate has -2.
