There are many polyatomic anions Many occur in families of names Start by learning the polyatomic ions ending with ate such as chlorate ClO 3 nitrate NO 3 2 sulfate SO 4 2 carbonate CO 3 and phosphate PO 4 3 The corresponding ite ion name has one less oxygen and the same charge For example chlorite ion is ClO 2 Polyatomic Ionic Formula Writing Name KEY Name Ions Formula sodium sulfate Na 1 SO4 2 Na2SO4 lithium phosphate Li 1 PO4 3 Li3PO4 aluminum acetate Al 3 C2H3O2 1 Al C2H3O2 3
An example is ammonium ion NH 4 It has five atoms one nitrogen and four hydrogens that share a charge of 1 The polyatomic ions remain intact and parentheses may be required when using subscripts For example ammonium chloride is NH 4 Cl and ammonium sulfide is NH 4 2 S Ammonium is the only polyatomic cation Common anions are shown Chapter 3 Ions Ionic Compounds and Nomenclature An ion is a small particle having an electrical charge Ions are either single charged atoms simple ions or small charged molecules polyatomic ions Examples of simple ions are Na Ca 2 Cl and S 2 Examples of polyatomic ions are NH
