Answer

Guidelines for Naming Chemical Compounds: 1. Follow the rules for naming acids when H is the first element in the formula. 2. If the compound is binary, generally the name ends with the suffix -ide. If the compound is a molecular binary compound, use prefixes to indicate the number of atoms. 3. When a polyatomic ion that includes oxygen is in the formula, the compound name generally ends in -ite or -ate. 4. If the compound contains a metallic cation that can have different ionic charges, use a Roman numeral to indicate the numerical value of the ionic charge in the compound. Guidelines for Writing Chemical Formulas: 1. An -ide ending generally indicates a binary compound. 2. An -ite or -ate ending means a polyatomic ion that includes oxygen is in the formula. 3. Prefixes in a name generally indicate that the compound is molecular. 4. A Roman numeral after the name of a cation shows the ionic charge of the cation.
