Electron flow is the action which occurs at the electrodes of galvanic cells.
A galvanic cell comprises of the electrolyte and electrodes. There are two
types of electrodes called the cathode and anode.
The cathode is the positive electrode found in electrochemical cells and
electrons flow from it to the anode. Negatively charged ions flow to the
cathode and reduction takes place in it.
The electrons from the cathode are then passed to the anode (negative
electrode) which gets oxidized and we can infer that oxidation takes place in
the anode. The flow of electrons helps to generate electricity.
