Yes, of course. But on that scale the electrons are 1/2 a mile in diameter and fill up the space. Neutrons are small, that can be measured by collisions. Protons are assumed to be the same size as neutrons. But electrons are huge by comparison. Exactly how huge depends on whether they are captured by atoms or free.

I don't think so. On that scale the electron wouldn't be the size of this period.
That's according to information I read just a few days ago.
If I can find a link, I'll post it.

It was my understanding that the space surrounding the nucleus is a "probability cloud," somewhere within which the electron could be located, not that the electron grows to fill that space. I also seem to recall something about the electron having wavelike properties. Oh, well. I'm not a physicist, and the only physics I use in daily life is that required to remember that DNA and denatured proteins migrate towards the red wire.

But electrons are huge by comparison.

Whether the electrons are very small or huge by comparison since the electron spins around the nucleous a billion or so times per second wouldn't centrifugal force send the electron zooming away from the atom or molecule? Unless as the article states the electrical forces here must be extremely powerful.
