◉ Anode. Answer: Part of the metal that corrodes. Oxidation occurs
at the anode
◉ Return Path. Answer: Connects cathode and anode and allows
passage of electrons generated at the anode to the cathode
◉ Electrolyte. Answer: Medium that conducts ionic (rather than
electronic) current
◉ Negative Electrode. Answer: Zinc case which corresponds to the
anode in a corrosion cell
