Naming Compounds with Transition Metals

The video tutorial explains how to name compounds containing transition metals, using Roman numerals to indicate the metal's oxidation state. It covers examples like FeCl3, CuBr2, and compounds with polyatomic ions such as CuSO4 and Ni(NO3)2. The tutorial emphasizes the importance of understanding the charges of ions to correctly name these compounds.
