Do protons, neutrons and electrons change shape?
If they don't: What shape are they individually? Are they irregularly shaped? Are they 'regularly shaped'? Spherical (like in textbooks, diagrams)? Cube-shaped? Prism-shaped? Are all protons/neutrons/electrons the same shape? Do some protons/neutrons/electrons have different shapes than other protons/neutrons/electrons respectively? Do protons and neutrons have the same shape when in atomic nuclei?
If they do: How do they change shape whilst maintaining constant mass? Is their volume constant? Can we predict their shapes or is it random? How do the subatomic particles change shape to not collide with each other? Do protons and neutrons change shape in the nuclei? Do electrons change shape in electricity when they drift through a circuit?
Either way, can we predict the amount of empty space taken up inside any given atom (the borders of the atom being the outline of its highest energy electron's orbital/subshell)? Can we find the volume of the subatomic particles themselves in order to find the amount of empty space? Do we know the area of space around a nucleus that the electrons physically cannot go outside of (the electrons themselves still have a small probability of falling outside their assigned orbitals) in order to find where an electron could be at any given moment? When alpha and beta radiation occur, how do the electrons in the atom take a position in such a way that the alpha/beta particles being ejected don't collide with the electrons orbiting the nucleus (do they change shape)?
