Ionic Compounds and Charges

The video tutorial explains how to name the ionic compound PbCl2. It begins by identifying the components: lead (a transition metal) and chlorine (a non-metal). The tutorial outlines the steps to name the compound, starting with the metal, followed by the non-metal with an 'ide' suffix. It emphasizes the importance of determining the charge of the transition metal, using the known charge of chlorine to deduce that lead must have a 2+ charge. This results in the name 'lead II chloride', with an alternative name being 'lead dichloride'. The video concludes by explaining how the Roman numeral indicates the charge of the lead.
