Neutron, neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinary hydrogen (whose nucleus has one proton and no neutrons). Along with protons and electrons, it is one of the three basic particles ma
1. Proton: positive charge 2. Electron: negative charge 3. Neutron: neutral charge Protons and neutrons stay in the nucleus, and they have nearly the same mass (the neutron is a little heavier). The atomic mass is the combined mass of the protons and neutrons in the nucleus. Differ...
magic number, inphysics, in the shell models of both atomic and nuclear structure, any of a series of numbers that connote stable structure. The magic numbers for atoms are 2, 10, 18, 36, 54, and 86, corresponding to the total number of electrons in filled electron shells. (Electrons ...

In the head-on collision between a neutron and a stationary proton (which has a mass essentially equal to the neutron mass), the proton is set into motion and the neutron comes to rest. Because the proton (unlike the neutron) is achargedparticle, it rapidly loses its energy through ...
to W. D. Harkins2by Glasstone3. It appears likely that it was not used by either Rutherford or Hawkins before about 1920. In both cases, the neutron was a hypothetical combination of a hydrogen nucleus (also called a ‘positive electron’ or ‘proton’) and an ordinary negative electron....
The constraint that real particles be produced in the final state is shown to lead to a depletion in the apparent value of the asymptotic total neutron cross section as determined from deuteron scattering. For pion, kaon or photon scattering this depletion is ∼ 5%. For electron scattering, ...
noticed a neutral radiation coming out. This neutral radiation could in turn knock protons out of the nuclei of other substances. Chadwick concluded that this radiation was a stream of neutrally charged particles with about the same mass as a proton; the neutron has a mass of 1.675 x 10-24...
Neutron Facts A neutron is a type of hadron. It consists of one up quark and two down quarks. Although the mass of a proton and a neutron are comparable, especially compared with the much lighter electron, a neutron is slightly more massive than a proton. A neutron has a mass of 1.6749...
