How does the standard cell potential tell you about whether 1) a species is oxidizing or reducing? 2) how strong of an oxidizing or reducing agent the species might be?

The standard cell potential helps to determine the oxidative and reductive strength of species. All the species that lie below the Standard Hydrogen Electrode in the standard cell potential table are stong oxidizing agents and are highly electronegative while those that are above the Standard Hydrogen Electrode are either weak oxidants or reducing agents
