Naming and Charges of Ionic Compounds

The video tutorial explains how to name the compound PbBr2, which is an ionic compound consisting of lead, a transition metal, and bromine, a non-metal. The process involves identifying the metal and non-metal, determining the charge of the transition metal, and using the appropriate naming conventions. The official name for PbBr2 is lead(II) bromide, although it is sometimes referred to as lead dibromide. The tutorial also covers how to write the formula from the name by understanding the ionic charges involved.
