Naming and Charges of Iron Compounds

The video tutorial explains how to name the compound FeCO3. It begins by identifying CO3 as a carbonate ion, a polyatomic ion, and recognizing iron as a transition metal. The tutorial then details the process of naming the compound by first writing the name of the metal, iron, followed by the polyatomic ion, carbonate. Since iron is a transition metal, its charge must be determined by considering the charge of the carbonate ion, which is 2-. This leads to the conclusion that iron must have a 2+ charge, resulting in the name iron(II) carbonate. The video concludes with a recap of the naming process.
