Naming Ions and Their Charges

This video tutorial introduces the unit on chemical formulas and compounds, focusing on differentiating between ionic and molecular compounds. It covers naming and writing ionic formulas, using molar mass and conversion factors, and understanding monatomic ions. The tutorial also explains how to name cations and anions, including the use of the Stock system for certain metals. By the end of the unit, students will be able to name and write chemical formulas, use conversion factors, and determine percent composition.
