Oxidation States and Ionic Compounds

The video tutorial explains how to name the compound V2S5. It begins by identifying vanadium as a transition metal and sulfur as a non-metal, leading to the naming of the compound as an ionic compound. The tutorial details the process of writing the names of the elements, adjusting the suffix for sulfur, and considering the oxidation number of vanadium. The oxidation number is calculated to ensure the compound's net charge is zero, resulting in the name vanadium 5 sulfide. The video concludes with a reference to additional resources for writing chemical formulas.
