Naming and Charges of Compounds

The video tutorial explains how to name the compound MN n32. It begins by identifying manganese as a transition metal and NO3 as the nitrate ion, a polyatomic ion. The tutorial then guides viewers through the process of naming the compound by first writing the name of the metal, manganese, followed by the polyatomic ion, nitrate. Since manganese is a transition metal, the video explains how to determine the charges on the ions, noting that the nitrate ion has a charge of 1-. With two nitrate ions, the total negative charge is 2-, meaning manganese must have a charge of 2+. The final name of the compound is manganese(II) nitride, with the Roman numeral indicating the charge of manganese.
