The video tutorial explains how to write the chemical formula for tin(IV) iodide. It begins by identifying the symbols for tin and iodide, noting that tin is a transition metal with a charge of 4+. The tutorial then discusses the iodide ion, which has a charge of 1-. To balance the charges, four iodide ions are needed to match the 4+ charge of tin, resulting in the formula SnI4. The video also covers how to name the compound using the formula, emphasizing the importance of the Roman numeral to indicate the charge of the transition metal.
