The monatomic nonmetal anions and their protonated forms usually exhibit the lowest possible oxidation number which gives them the ability to transfer electrons back to other materials (act as reducing agents).
Nonmetals can be divided into two groups based on their redox properties.
Very electronegative nonmetals
These nonmetals have EN > 2.8 and are good oxidizing agents.
F2 will oxidize all metals and most other substances. It must be stored in either nickel or copper containers because the fluorides of these metals form a film passivating the metal surface.
The other halides are successively less oxidizing.
AlthoughO2 is a strong oxidizing agent, its oxidizing reactions are usually slow kinetically. Many flammable materials will exist in the presence of air until a flame or spark starts the reaction. The very electronegative nonmetals are poor reducing agents.
Electronegative nonmetals
These nonmetals have electronegativities between 1.9 and 2.8. These elements have few laboratory uses as oxidizing agents.
Sulfur serves as an oxidizing agent for some electronegative metals. For example, the tarnishing of silver is the formation of silver sulfide.
The electonegative nonmetals have moderate to strong reducing properties.
