Answer:
Nitric acid, halogens
Explanation:
Such types of atoms, molecules or ions that accept or gain the electrons are called oxidizing agents. These agents or species are thus reduced in the chemical reaction. Oxidizing agents may be neutral atoms such as chlorine, bromine, and may be compounds or ions such as nitric acid, potassium nitrate, Fe 2+ ion and many more. Such type of reaction in which oxidation and reduction take place is called a redox reaction.
