I have a question about atom size VS particle size. The size of an electron, proton, and neutron (or really how much space they occupy) as compared to the amount of space they take up when they are assembled as an atom. I read somewhere that the particles are actually like millions of times smaller that the volume occupied when they are part of an atom. The electron is orbiting very far from the nucleus and all of the particles are much smaller that the volume of a functioning atom. Has anyone figured out exactly how much the increase in volume actually is? I once heard someone say that if you could bring Lake Superior down to absolute zero, it would disappear before your eyes. The space occupied by the unbound atomic particles would be millions of times less than when the particles were part of functioning atoms. All of the mass would still be there but you couldn’t see it. Is this true?
