Equations can be balanced by using the half-reaction method. which step should be completed immediately after finding the oxidation states of atoms?

The correct answer is to find the half reactions.

Explanation:

After determining the oxidation states of atoms, one should determine the half reactions. The half reactions are illustrated by the modification in the oxidation states of the atoms. For example, if there is O with oxygen state 0 in the left side and with oxidation state 2- in the right side, then there one can have a half reaction (reducing reaction). Similarly, if Cu is in the left side with oxidation state 0, and on the other side with the oxidation state 2+, then one can get another half reaction (oxidation reaction).
