Roman Numerals in Chemical Compounds

This video tutorial explains how to name the compound SNHP42. It begins by identifying SN as a transition metal, tin, and recognizing the presence of a polyatomic ion, HPO4, which is hydrogen phosphate. The tutorial guides viewers through naming the compound by first writing the name of the transition metal, followed by the polyatomic ion. It also covers determining the charge of the compound, emphasizing the use of Roman numerals to indicate the charge of the transition metal. The video concludes with a summary of the naming process.
