This video tutorial explains how to write the formula for nickel(III) bromide. It begins by identifying the element symbols for nickel and bromine, highlighting that nickel is a transition metal with a charge of three plus. The video then discusses the formation of ionic compounds, emphasizing the need to balance charges to achieve a neutral compound. By applying a subscript of three to bromine, the charges are balanced, resulting in the formula NiBr3. The tutorial concludes with a brief thank you from Dr. B.
