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.
All the neutrons in all the elements have the same mass and dimensions. The neutron mass is 1, 674 927 29.10-27 kg.
Very small- only a few miles in diameter but ten times as dense as the sun.
neutron star
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
The neutron is a part of the atom, therefore it is smaller.
electron and neutrino are formed by the decay of neutron.
Ernest Rutherford described the existence of the neutron.
neutron star
Considering a neutron star is about the size of a city, a subgiant is way bigger.
Neutron stars range in size from 20 to 40 kilometers (12 to24 miles) in diameter.
Neutron degeneracy pressure, in which the neutrons themselves prevents further collapse.
about 1/3 of a neutron star
No, They are nearly exactly identical in size.
Considering neutron stars are about the size of a city, sub giants are much bigger
A neutron star is about the size of a small city. About 12km across but with the mass of about 2 Suns.
prove that size of an atom is 10,0000 times the size of neuclous
electron is the smallest
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.
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.
