Describe the redox reaction. Check all that apply. 2Na(s) + Cl2(g) → 2NaCl(s)

Sodium changes from oxidation state 0 in Na(s) to +1 in NaCl, so each sodium atom loses an electron and is oxidized. Chlorine changes from 0 in Cl₂ to −1 in NaCl, so chlorine gains electrons. Sodium transfers electrons to chlorine; therefore, chlorine is the oxidizing agent, not the reducing agent, and sodium chloride is the product rather than the oxidizing agent.
