What is Neutron:
A neutron is a subatomic particle that is characterized by having no electrical charge. That is, it is one of the components that make up the atom, and it is located in the nucleus.
In effect, neutrons and protons (positively charged) make up the nucleus of the atom, in turn called the nucleon. The nucleon, and therefore its components, is present in all atoms, with the exception of hydrogen.
It was in 1932 when the researcher James Chadwick discovered the neutron, although Ernest Rutherford had already suggested the existence of neutrons as a scientific hypothesis.
Unlike the electron that cannot be subdivided, neutrons are made up of three particles called quarks. These quarks are distributed as follows:
- two down quarks (which have an electric charge of -1/3) and
- an up quark (with +2/3 charge).
By adding both electric charges, the final result is zero coulombs, so the particle becomes neutral.
Because their charge is neutral, neutrons can interact with protons without electromagnetic repulsion between them. This interaction is called a strong nuclear force.
The mass of the neutrons is 1.675x10-27 Kg or 0.0009396 GeV (gigalectronvolt).
Neutrons are only stable as long as they remain in the nucleus. Outside of this, they are characterized by instability. When this happens, in a matter of minutes the neutrons decay into an antineutrino and an electron, and from there, finally, a proton results.
