Answer

Brief Explanations:

In balancing redox - half - reactions, the first step after writing the half - reactions is to show the number of electrons being lost or gained. This helps in determining the stoichiometry for combining the half - reactions to balance the overall reaction. For the given half - reactions $Au^{3 +}\to Au$ and $I^-\to I_2$, we need to identify the electron transfer.

Answer:

Show the number of electrons being lost or gained.
