Monoatomic ions (ions made up of only one atom) are named by changing the end of the element name to -ide for example: bromine (Br) becomes bromide (Br - ) tellurium (Te) becomes telluride (Te -2 ) sulfur (S) becomes sulfide (S -2 )

 When naming an ionic compound, you first give the name of the cation element, then the anion with the -ide ending.  For example; NaCl is sodium chloride Lets name the compounds from the first practice slide….

Now practice: Ca 2+ + O 2- → CaO 3Na + + N 3- → Na 3 N 3Ca N 3- → Ca 3 N 2

Now practice: Ca 2+ + O 2- → CaO Calcium Oxide Na + + N 3- → Na 3 N Sodium Nitride Ca 2+ + N 3- → Ca 3 N 2 Calcium Nirtide

Polyatomic Ions  Polyatomic ions are ions made up of more than one atom  There are 15 polyatomic ions (ions made up of more than one atom)  I will give you the chart on page 178 of the text for the test, so when you see the formula, you need to be able to tell me the name.

 Here are some of them….  OH- hydroxide  SO 4 2- sulfate  SO 3 2- sulfite  O 2 2- peroxide  NO 2 - nitrite  NO 3 - nitrate  MnO 4 - permanganate

The same rules apply when dealing with polyatomic ions. (remember, the charge associated with the polyatomic ion applies to the entire ion) K + + CN - → KCN 2Na + + O 2 2- → Na 2 O 2 Mg NO 2 - → Mg(NO 2 ) 2 (by putting parenthesis around the Nitrite portion of the compound, the following subscript tells us that there are 2 nitrite ions for every one Magnesium ion in this compound)

Naming Compounds that have TRANSITION METALS  because transition metals can have more than one charge, you must include the charge of the metal, in the form of a Roman Numeral, in the name. For example… Fe OH -  Fe(OH) 2 The product is named Iron (II) Hydroxide Fe OH -  Fe(OH) 3 This product would be named Iron (III) Hydroxide
