Naming and Charges of Copper Iodide

The video tutorial explains how to name the chemical compound CUI. It starts by identifying copper as a transition metal and iodine as a non-metal, forming an ionic compound. The tutorial outlines the steps to name the compound: naming the metal (copper) and the non-metal (iodine), then replacing the ending with 'ide' to form copper iodide. Since copper is a transition metal, its charge is indicated with Roman numerals, resulting in the name copper(I) iodide.
