1 Chapter 2: Naming Inorganic Compounds To name a compound you must first decide whether the substance is an ionic or molecular compound. Ionic compounds are easily recognized since they usually contain both metallic and non-metallic elements. The most common exception to this rule are ionic compounds containing the ammonium ion, NH 4 + , such as (NH 4 ) 2 CO 3 or NH 4 Br which contain no metal ions. Molecular compounds typically contain only non-metallic atoms (and metalloids). To successfully follow the rules, however, you must be first learn the names of common ions. Names of ionic compounds do not give the number of each type of ion in the formula: the chemist is supposed to be able to figure that out from his/her knowledge of ion charges and the requirement that salts be neutral (and thus have a sum of zero for the ion charges in the formula). Binary compounds of the non-metals are named following other guidelines. Note that when naming these molecular compounds, the number of atoms of a given type is commonly indicated with a prefix (di-, tri-, tetra, etc.). ___________________________________________________________________ Exercises 1. Complete the following chart of corresponding ion names and formulas.
