If the Nucleus was the size of a small marble, the Electron is about 100 Yards away.
Some would say "Wow, so much empty space"
I say look at Quantum Mechanics and String Theory and "see" that there is "NO" empty space ;-)
Mass equals:
Proton: 1.6726*10-27 kg
Neutron:1.6749*10-27 kg
Electron 0.0009*10-27 kg

An atom's size is determined by the compnents of the atom - it's protons, neutrons and electrons. Only the protons and neutrons are in the nucleus. The elctrons exist in "shells" outside of the nucleus. Therefore, the atom's size and density is larger than its nucleus, and the size of both depends on these 3 particles - how many and where they are.

The nucleus is very small compared to the overall size of the atom.
As for density, the nucleus is MUCH more dense than hte entire atom.
