e- returning to metal

Postby Jose Munoz 1D » Sun Apr 15, 2018 10:38 pm

When the electrons are returning to metal, do the e- release a photon, or is it another form of energy?

The electrons are displaced by the photons if the photons have a high enough energy, aka "threshold energy". The photons and electrons are not interchangeable and are definitely different particles.

When an electron is emitted from a metal, you are actually making the metal less stable than it was due to losing charge neutrality. Since metal is a good conductor, most likely it will replace the electron lost very quickly in that location by conducting the electron from somewhere else. Because it is also less stable, any recombination of electron with the now positive metal would actually be more stable so you would actually lose energy not try to release energy.
