Naming Ionic Compounds: From Formula to Name

This video tutorial by Dr. Kent on GetChemistryHelp.com continues the series on ionic compounds. It covers naming monoatomic and polyatomic ions, converting names to formulas, and vice versa. The lesson explains fixed and variable charge metals, detailing how to determine metal charges in compounds using anion charges. Several examples are provided to illustrate the naming process of ionic compounds. The tutorial concludes with a prompt for further practice problems.
