Which conducts electrons from the anodic sites to cathodic sites?

• A. Metallic path
• B. Electrolyte
• C. Galvanic path
• D. Anode conductor

Answer: (A)

In a corrosion cell, electrons move through a conductive metal path that directly connects the anodic and cathodic sites. The anodic regions oxidize and release electrons, and those electrons travel through the metal itself to reach the cathodic sites where reduction occurs. The electrolyte surrounding the metal supports ion movement to balance charge, but it does not carry electrons between sites. While a galvanic interaction explains why a corrosion cell forms in the first place, the actual transport of electrons happens through the metallic path. Anode conductor isn’t a standard term for the electron route, so the metallic path best describes how electrons are conducted from anodic to cathodic areas.
