Radius of atom parts
Do anybody know the radius of an electron, proton, or neutron? I understand there are smaller things like quarks, and everything, but as a general size, does anybody know the radius of these parts of an atom?

Electron and quarks are so far pointlike particles. The radius of the proton and/or the neutron depends on how you actually define such a thing. Typical values for the radius of nucleon are of the order 1 fm, which is [tex]10^{-15}[/tex] m.
