Naming and Charges of Polyatomic Ions

The video tutorial explains how to name the compound MnH32. It begins by identifying manganese as a transition metal and H3 as the bicarbonate ion. The process involves writing the metal's name from the periodic table and the polyatomic ion's name. Since manganese is a transition metal, its charge must be indicated using Roman numerals. The tutorial concludes with the full name: manganese(II) bicarbonate.
