The relationship between a cathode and an anode involves
a. protons.
b. diodes.
c. electrons.
d. neutrons.

Cathode and anode always go together in electrochemical reactions. An example of this is the lead battery. The lead battery contains a chemical that is involved in the chemical reaction. The chemical reaction in the battery causes a buildup of electrons in the anode. And because the electron buildup in the anode is full, its only place to go is the cathode. The movement of the electrons from anode to cathode is caused by the chemical reaction present in the battery. There will be a movement until the chemical runs out. If the chemical runs out, the electrons stop moving. The answer is c.

The correct answer should be b let me know if i’m wrong
