The video tutorial explains how to write the chemical formula for manganese(IV) bromide. It begins by identifying the symbols for manganese and bromine, noting their charges. Manganese has a 4+ charge, while bromine has a 1- charge. To balance the charges and form a neutral compound, four bromine atoms are needed for each manganese atom, resulting in the formula MnBr4. The tutorial emphasizes the importance of balancing charges to achieve a net charge of zero.
