I’ve understood that electrons move in a 3D field outside the nucleus and that they are quite far away from the nucleus itself (in relation to the atom scale).
What would happen if you pushed them out of this moving field of theirs, closer to the nucleus?
This happens in neutron stars.
The zillions of Gs of gravity squishes atoms together, until electrons and protons are forced together, and become neutrons, Of course, at those densities, a spoonful of neutron star weighs as much as Mt. Everest,
Ooh okay they just change into another atom-piece-particle when added together!
