I am wondering what would be the result if a piece of copper were to suddenly lose all its valence electrons, or in other words, if a piece of copper was to suddenly become a collection of copper cations.
Since the Coulomb force between all the positively-charged copper atoms/cations should immediately start to push the copper anions away from one another, this piece of copper should either immediately expand in physical size or perhaps begin to disintegrate, but what will actually occur I really don't know.
As far as what mechanism could suddenly force out all the valence electrons within a piece of copper, such as a copper strip for example, please reference the drawing below:
This drawing of mine is showing a conceptual electrical apparatus that would suddenly squeeze out the valence electrons within a copper strip using two very strong electrostatic forces generated by two negatively-charged parallel plates. (Offhand, how exactly this apparatus would be constructed mechanically I have no idea at this point. I'm mostly interested in finding out if the working principle of it is a sound one.)
It is showing 50 kV as a voltage number because I believe that should generate a pretty strong electrostatic force, but I really don't know this because I'm not an electrical engineer and my knowledge of electrostatics, electric fields, and Coulomb forces is very limited. Also, this drawing is showing this apparatus within a vacuum chamber to take away the dielectric effect that air would have if it is present between the spaces between the copper strip and the parallel plates.
The working principle of this apparatus is that once the HV DC power supply is turned on, the valence electrons within the copper strip will be suddenly compressed towards its center and they should quickly exit out of the copper strip through an attached ground wire that would be soldered to the center of it.
This sudden expulsion of valence electrons should then instantly turn the copper strip into a collection of copper cations and the Coulomb force acting between all these cations should result in some sort of sudden physical change to the copper strip.
This is not a homework question. I am asking it simply out of my own scientific curiosity and to improve my overall understanding of electrostatics.
What would happen to a piece of copper if it were to suddenly lose all its valence electrons?
All the electrodes would need to be thickly coated with an electrical insulating material that would stop any electrical current between the electrodes yet would also have a low dielectric constant to allow electrostatic force to pass through it.
It would also have to be a material that could withstand very high electrical voltages so it doesn't have a quick dielectric breakdown. I believe the only material that could be used is diamond. If all the electrodes could be coated with a thick layer of poly diamond film, then I think this experiment with copper would work.
