Hello!

Can you tell me please what is the natural evolution of an electrode that acquires electrons?

I assume that:
1) the electrodes ability to acquire more electrons is reduced due to being gradually charged negatively more and more
2) the electrode will be charged negatively at the point of the electron acquisition but these electrons will move to other points of the electrode as they are mutually repulsed so that the charge of the electrode will diffuse from the point of the electron acqusition to the total mass of the electrode

Are these phenomena what is really happening?
Is there anything else?

Thanks!

This is fairly close to true... just replace "gradually" with "quickly"! It doesn't take many electrons to saturate the electrode.

Ordinarily the electrode passes the electrons on to some sort of circuit.
