Verified step by step guidance1
Understand the concept of reduction in redox reactions: Reduction is a chemical reaction that involves the gain of electrons by an atom, ion, or molecule.
Recall the mnemonic 'OIL RIG' which stands for 'Oxidation Is Loss, Reduction Is Gain' of electrons. This helps in remembering that reduction involves gaining electrons.
Consider the context of the question: It asks whether reduction is the process of adding electrons to an atom or molecule.
Apply the definition of reduction to the question: Since reduction involves the gain of electrons, adding electrons to an atom or molecule is indeed reduction.
Conclude that the statement 'Reduction is the process of adding electrons to an atom or molecule' is true based on the definition and understanding of reduction.
