    • 4.1: 4.1-Types of Chemical Bonding
      Atoms have a tendency to have eight electrons in their valence shell. The attraction of oppositely charged ions is what makes ionic bonds.
    • 4.2: 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.
    • 4.3: Formulas for 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.
    • 4.4: Ionic Nomenclature
      Each ionic compound has its own unique name that comes from the names of the ions. After learning a few more details about the names of individual ions, you will be a step away from knowing how to name ionic compounds. This section begins the formal study of nomenclature, the systematic naming of chemical compounds.
    • 4.5: Transition Metal Ion Formation
    • 4.6: Formula Mass
      Formula masses of ionic compounds can be determined from the masses of the atoms in their formulas.
    • 4.7: Characteristics of Ionic Compounds
      Ionic compounds are composed of cations and anions that are strongly attracted to each other. Hence, ionic solids have very high melting points and are extremely hard. When dissolved in water, the ions separate from each other, allowing them to form electrolyte solutions.
