In a redox reaction, the oxidizing agent undergoes oxidation the reducing agent undergoes reduction the oxidizing agents undergoes reduction the oxidizing agent loses electrons

-

Oxidation involves loss of electrons.

Reducing agents undergo oxidation and thus lose electrons in a redox reaction.

Metals are good reducing agents due to low value of ionization enthalpy.

Reduction involves gain of electrons.

Oxidizing agents undergo reduction and thus gain electrons in a redox reaction.

Nonmetals are good oxidising agents due to high value of electron affinity.
