Naming and Charges of Tin Compounds

The video tutorial explains how to name the compound SnS2. It begins by identifying tin as a transition metal and writing its name as it appears on the periodic table. The non-metal, sulfur, is named by replacing its ending with 'ide'. The charge on tin is determined by considering the charge of sulfur, leading to the use of a Roman numeral to indicate tin's charge. The final name of the compound is tin(IV) sulfide.
