검증된 단계별 안내1
Understand the concept of reduction: In chemistry, reduction refers to the gain of electrons by an atom or molecule. This is part of a redox (reduction-oxidation) reaction.
Identify the role of electrons: During reduction, electrons are added to the atom or molecule, which decreases its oxidation state.
Clarify the misconception about protons: Reduction does not involve the gain or loss of protons. Protons are part of the nucleus and are not directly involved in redox reactions.
Differentiate between reduction and oxidation: While reduction involves gaining electrons, oxidation involves losing electrons. These processes occur simultaneously in redox reactions.
Apply the concept to the problem: Based on the definition of reduction, the correct answer is that the atom or molecule gains electrons.
