its difficult to talk about size, when talking about such particles. Maybe someone will correct me, but my understanding is that electrons and protons have no size: we say they are point particles. They have a probability wave which shows where they are likely to appear, but I don't think they actually have a volume as, in the same way, a swimming pool or a car would have.
We can estimate the size of a nucleus, which consists of neutrons and protons, then divide that volume by the total number of nucleons, which would probably give a value of 10^-15m, but can you actually say that a free floating neutron has a volume? I don't know.
Electrons certainly dont. We say they are point charges.

What is about 20 km in size?
neutron star
Which is smaller proton neutron or electron?
The Electron is by far the smallest of the three. Protons are the same size and mass of the Neutron, and they are more than 1,800 times the mass of the electron.If you don't understand that, here's some form of a table of the masses of the 3 particles:Electron: 1/1800 Neutron = 1/1800 ProtonNeutron: 1800 Electrons = 1 ProtonProton: 1800 Electrons = 1 Neutron
What is smaller an atom or an atom's neutron?
The neutron is a part of the atom, therefore it is smaller.
What species are formed by the decay of neutron?
electron and neutrino are formed by the decay of neutron.
What scentisit described the existence of the neutron?
Ernest Rutherford described the existence of the neutron.
What is about 20 km in size?
neutron star
What prevents neutron stars from contracting to a smaller size?
Neutron degeneracy pressure, in which the neutrons themselves prevents further collapse.
How small are neutron stars?
Neutron stars range in size from 20 to 40 kilometers (12 to24 miles) in diameter.
Is the neutron larger then a proton?
No, They are nearly exactly identical in size.
What is the size of a black hole?
about 1/3 of a neutron star
How was neutron discovered describe its main characteristic?
prove that size of an atom is 10,0000 times the size of neuclous
Which is smallest in size an ion electron neutron or atom?
electron is the smallest
Is a neutron star bigger than a planet?
Yes, a neutron star is much more massive and denser than a planet. Neutron stars are formed from the remnants of massive stars and are typically only a few kilometers in diameter, while planets can be thousands of kilometers in size.
What is the size of electron proton and neutron?
The electron is the smallest having about 1/1836th the mass of a proton or neutron, which means that basically an electron has no mass. The neutron and proton weigh the same both having a mass of 1.
what star is smaller neutron star or white dwarf star?
A neutron star is smaller, but has a greater mass. A typical white dwarf is about the size of a terrestrial planet. A typical neutron star is a few miles across.
What particles in the atom are similar in size?
The dimensions of a proton is approximately similar to that of a neutron.
How big a neutron stars?
The diameter is about 20 or 30 km. About the size of a city.
