Naming Simple Binary Ionic Compounds

This video tutorial explains how to name simple binary ionic compounds, focusing on elements with predictable valence electrons and no transition metals. It covers the general rules for naming cations and anions, provides examples of converting chemical formulas to names and vice versa, and includes detailed examples like potassium oxide, calcium chloride, magnesium chloride, and aluminum oxide. The video concludes with a summary and directs viewers to additional resources for more complex naming involving transition metals.
