Released electrons

Postby NatalieSDis1A » Sat Apr 14, 2018 11:23 am

What happens after an electron is released from a metal in the photoelectric experiment. Does it eventually return to the cation? In the case of the threshold energy equaling the energy of the photon, does the electron release and immediately rejoin the cation? I'm trying to picture the experiment in my head and this part is confusing me.

In the experiment, there is two plates of metal connected by wiring to create a circuit. Since the electrons are knocked off of one metal, the freed electrons moves through the circuit to the second plate. The original plate that had its electrons knocked out would become slightly positive, thus attracting back its electrons from the other metal plate. All in all, the electrons should end up back into the original metal plate.
