Question

which of the following is transferred in oxidation-reduction reactions? energy protons neutrons electrons

Explanation:

In oxidation - reduction (redox) reactions, the key process is the transfer of electrons. Oxidation is defined as the loss of electrons, and reduction is the gain of electrons. Protons are part of the atomic nucleus and do not get transferred in redox reactions. Neutrons are also in the nucleus and are not involved in the transfer process of redox reactions. Energy can be released or absorbed in redox reactions, but it is not the substance that is transferred in the fundamental sense of the redox process (the transfer of electrons drives the energy changes).

Answer:

electrons (the option with "electrons" as the text)
