how can oxidation numbers help you determine a redox reaction? when are oxidation numbers used instead of a valence number?

Explanation:

Oxidation numbers help identify redox reactions as a change in oxidation numbers indicates electron transfer. Oxidation numbers are used instead of valence numbers when dealing with compounds where valence concepts are insufficient, like in complex ions or compounds with non - integer valences. They provide a more precise way to track electron distribution and changes in chemical reactions.

Answer:

Oxidation numbers help determine redox reactions by showing electron transfer through changes in their values. They are used instead of valence numbers when valence concepts are inadequate, such as in complex ions or non - integer valence cases.
