If a proton and neutron have a mass of roughly 1.67e-27 kg . And a proton has a diameter of 1.65e-15 ..
Is the diameter of a neutron the same?

For all intents and purposes they are about the same. But concepts like diameter or radius in the context of small spheres, like ball-bearing in our everyday experience, are meaningless when applied to subatomic particles.nuby said:If a proton and neutron have a mass of roughly 1.67e-27 kg .

It will be hard and long to make sens of such a concept in the case hadrons. It is doable, it has been done, but there is virtually no experiment shedding light on this specific approach to hadron structure.nuby said:The "diameter" is more of a orbital boundary, correct?

I am not too sure about those agruments. What is the Compton wavelength of a u or d quark ? How does it compare with the size of a nucleon ? What can we conclude about the semi-classical approximation of a static-potential like confinement scenario, such as t'Hooft's dual-color-superconducting model of the vacuum ? Can we re-interpret this model in terms phase transitions a la Gribov ?Mr.Slava said:Usually the linear size of charged particle is Compton wavelength (1.65e-15 m is c.w. of a proton)
[tex]\lambda_C = \frac{\hbar c}{m c^{ 2 }}[/tex]
Therefore if neutron had been charged its size would has been equal to proton size, proton and neutron have about same [tex]\lambda_C[/tex] as [tex]m_{p} \approx m_n[/tex]. Your question is not trivial because size of a particle is defined trough forces of its interactions.

esbo said:I was surprised to find a neutron weighed more than a proton as I always thought a proton as a neutron with a positive electron inside it (or something like that).
But then maybe a neutron is is a proton with an electron inside it?
Actually if you look at the atomic weights a neutron is probably a proton with three electrons stuffed inside it.
Has this been confirmed by atom bashing?
Maybe you can explain us what you know about particle physics ?jhmar said:The whole question of particle structure is unresolved.
Sorry, I was not clear.malawi_glenn said:I don't know where the boarder lies between "own theories" and "own/speculative theories" that is mentioned in the forum rules.
The size of a neutron is slightly larger than that of a proton. This is because a neutron contains one additional subatomic particle, the neutral charge carrier known as the neutron. The exact size of a neutron can vary, but it is typically around 0.8 femtometers (fm) while a proton is approximately 0.7 fm.
Neutrons and protons are considered to be similar in size because they are both classified as baryons, which means they are made up of three quarks. The quarks inside a neutron and a proton are the same type (up and down quarks), but they have different numbers and arrangements, resulting in slightly different sizes.
The size of a neutron and proton is not constant. Their sizes can vary depending on the energy state and environment in which they exist. Additionally, in high-energy collisions, neutrons and protons can break down into smaller particles, resulting in even smaller sizes.
Knowing the size of a neutron and proton is important in understanding the structure of the atom and the fundamental particles that make up matter. It also helps in studying nuclear reactions and the behavior of particles in high-energy environments, such as in particle accelerators.
Scientists measure the size of a neutron and proton using a technique called scattering experiments. This involves firing particles, such as electrons or protons, at a target containing neutrons or protons and measuring the scattering pattern. By analyzing the pattern, scientists can determine the size and structure of the particles being studied.
