3.1: Prelude to Ionic Bonding and Simple Ionic Compounds We will see that the word salt has a specific meaning in chemistry, but to most people, this word refers to table salt. 3.2: Ions Atoms can gain or lose electrons to form positively charged or negatively charged species called ions. 3.3: Ions of Some Common Elements The periodic table can be used to determine ion charge. 3.4: 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. 3.5: 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. 3.6: 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. 3.E: Ionic Bonding and Simple Ionic Compounds (Exercises) These are homework exercises to accompany Chapter 3 of the Ball et al.
