Oxygen

OO 2 molecular oxygen
Common oxidizing agents are oxygen, hydrogen peroxide and the halogens.
It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.

Hydrogen peroxide

H 2 O 2 peroxideH 2 0 2
Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. Hydrogen peroxide (H 2 O 2 ) and other inorganic peroxides, Fenton's reagent
It is used as an oxidizer, bleaching agent and antiseptic.

Combustion

burningignitionincomplete combustion
Combustion, many explosives, and organic redox reactions involve atom-transfer reactions.
Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Redox

oxidationreductionoxidized
In chemistry, an oxidizing agent (oxidant, oxidizer) is a substance that has the ability to oxidize other substances — in other words to cause them to lose electrons.
The word oxidation originally implied reaction with oxygen to form an oxide, since dioxygen (O 2 (g)) was historically the first recognized oxidizing agent.

Permanganate

MnO 4 − MnO 4 permanganate ion
Examples include (permanganate), (chromate), OsO 4 (osmium tetroxide), and especially (perchlorate). Permanganate compounds such as potassium permanganate
A permanganate is the general name for a chemical compound containing the manganate(VII) ion, . Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent.

Perchlorate

perchloratesClO 4 ammonium perchlorate
Examples include (permanganate), (chromate), OsO 4 (osmium tetroxide), and especially (perchlorate). Chlorite, chlorate, perchlorate, and other analogous halogen compounds
Perchlorate salts are mainly used for propellants, exploiting properties as powerful oxidizing agents and to control static electricity in food packaging.

Ozone

Ozone is a powerful oxidant (far more so than dioxygen) and has many industrial and consumer applications related to oxidation.

Chlorine

Clchlorine gaschlorinated
Fluorine (F 2 ), chlorine (Cl 2 ), and other halogens
It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine.

Chemical reaction

reactionchemical reactionsreactions
In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction that removes one or more electrons from another atom.
Redox reactions can be understood in terms of transfer of electrons from one involved species (reducing agent) to another (oxidizing agent).
