Ionic Compounds and Their Properties

The video tutorial explains how to name the compound PbO2, which is an ionic compound with a transition metal. It starts by identifying lead as the metal and oxygen as the non-metal. The tutorial then describes the process of naming the compound as lead oxide, replacing the ending with 'ide'. It further explains how to determine the charge on lead, which is a transition metal, by considering the charge of oxygen. The use of Roman numerals to indicate the charge of lead is also covered, resulting in the name lead(IV) oxide. Finally, the tutorial verifies the formula PbO2 by balancing the charges.
