Redox reactions involve a transfer of which of the following from one atom to another?

• A. Neutrons
• B. Electrons
• C. Protons
• D. Photons

Answer: (B)

Verified step by step guidance

1. Understand that redox reactions are chemical processes involving the transfer of particles between atoms or ions.
2. Recall that redox stands for reduction-oxidation, where one species loses electrons (oxidation) and another gains electrons (reduction).
3. Identify that electrons are the subatomic particles transferred during redox reactions, not neutrons, protons, or photons.
4. Recognize that neutrons and protons are components of the atomic nucleus and do not typically move between atoms in chemical reactions.
5. Conclude that the correct answer is electrons, as they are responsible for the transfer of charge in redox reactions.
