Redox comes from the combination of the word reduction and oxidation. The first thing we have to learn in this lesson is what they call the redox numbers. They are numbers that are assigned, much like ions. In fact, they mean the same thing as the ion charges but they are assigned to different elements in a slightly different way.reduction definition: 1. the act of making something, or of something becoming, smaller in size, amount, degree….
