- 6.1: Ions
- Ions can be positively charged or negatively charged. A Lewis diagram is used to show how electrons are transferred to make ions and ionic compounds.
- 6.2: Ions With Variable Charges
- Some cations have multiple charges and are named accordingly with the use of Roman numerals in parentheses to indicate the particular charge of the cation.
- 6.3: Polyatomic Ions
- Proper chemical formulas for ionic compounds balance the total positive charge with the total negative charge. Groups of atoms with an overall charge, called polyatomic ions, also exist.
- 6.4: The Crystaline Struture of Ionic Compounds
- Proper chemical formulas for ionic compounds balance the total positive charge with the total negative charge. Groups of atoms with an overall charge, called polyatomic ions, also exist.
- 6.5: Naming Ionic Compounds
- Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses. Ternary compounds are composed of three or more elements.
