Naming Ionic Compounds and Polyatomic Ions

Professor Dave explains how to name ionic compounds by understanding ion charges and their combinations to form neutral compounds. He discusses the periodic table's role in determining common ion charges, the rules for naming ionic compounds, including the use of suffixes and Roman numerals for oxidation states, and the naming of binary covalent compounds using prefixes.
