In many cases, it does not matter which element is balanced first and which is balanced last, as long as all elements have the same nuer of atoms on each side of the equation. However, if elemental forms appear in an equation (i.e. Na, Zn, O 2 , H 2 , Cl 2 , etc), it is often easier to balance the equation, by leaving the elemental forms to be balanced last.
