Ionic Charges and Naming Compounds

The video tutorial explains how to find the ionic charge for transition metals. It begins with an overview of the periodic table trends and then delves into a more detailed periodic table, highlighting transition metals. The tutorial provides examples, such as copper oxide, iron oxide, copper chloride, iron sulfide, and zinc chloride, to demonstrate how to determine ionic charges by analyzing the compounds they form. The video emphasizes the importance of understanding the charges of elements they bond with to deduce the ionic charge of transition metals.
