Objectives To learn the names of common polyatomic ions To learn to name compounds containing polyatomic ions To learn how the anion composition determines an acid’s name To learn the names for common acids To learn to write the formula for a compound, given its name

A. Naming Compounds That Contain Polyatomic Ions Polyatomic ions are charged entities composed of several atoms bound together. They have special names and must be memorized.

A. Naming Compounds That Contain Polyatomic Ions Naming ionic compounds containing polyatomic ions follows rules similar to those for binary compounds.

B. Naming Acids An acid is a molecule with one or more H+ ions attached to an anion.
