Answer:
Most oxidation-reduction (redox) processes involve the transfer of oxygen atoms, hydrogen atoms, or electrons, with all three processes sharing two important characteristics: (1) they are coupled—i.e., in any oxidation reaction a reciprocal reduction occurs, and (2) they involve a characteristic net chemical change— .
Electrons will be transferred during redox reaction.
The electron is subatomic particles which are placed in surrounding the nucleus. Electrons carry negative charge.
Redox reaction involve the transfer of electrons between intermediates. A redox reaction occurs when the oxidation states of the substrate change. The removal of electrons or even a rise in the oxidation state of such a chemical or its atoms is referred to as oxidation. The acquisition of electrons or a lowering in the oxidation number of a chemical or the atoms inside it is referred to as reduction.
Hence the answer will be electron
