Which type of agent do nonmetals with high electronegativity typically represent?

Nonmetals with high electronegativity typically act as oxidizing agents because they have a strong tendency to attract electrons. Electronegativity is a measure of an atom's ability to attract and hold onto electrons within a chemical bond. Nonmetals, especially those with high electronegativity like fluorine, chlorine, and oxygen, are very effective in accepting electrons from other substances during chemical reactions.

When a high electronegativity nonmetal gains electrons, it is reduced, while simultaneously causing another substance to lose electrons, which is oxidation. This electron acceptance is a key characteristic of oxidizing agents—they facilitate the oxidation of other substances by pulling away their electrons. As a result, they are essential participants in redox reactions where the transfer of electrons occurs.

Nonmetals that are not highly electronegative do not have the same tendency to act as oxidizing agents, and substances that serve other roles like reducing agents, neutral agents, or inert agents do not possess the same electron-attracting properties common to highly electronegative nonmetals.
