I don’t think i’m getting what you said or you are not getting what I said. It makes no sense to me(not about charge attract thing, but the overall argument). Does the nucleus accelerate when there is electrone cloud on all directions? It just cancels out. But i don’t think nucleus will freely move if temperature is low. You don’t apply pressure to the nucleus, you apply it to the electron cloud around. Nucleus won’t fly off the electron cloud because they are bound by electrons attracting in all directions. Only way I can see neutrons moving is when enough temperature is supplied. Otherwise its just squishing electrons into the nucleus(before squishing nucleii together). I don’t understand why you keep it does not matter because there is so much pressure or so. Clarify why you said so
