Neutron vs. Neutrino — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on April 15, 2024
Neutrons are uncharged particles within atomic nuclei, essential for atomic stability, whereas neutrinos are neutral, nearly massless particles that interact minimally with matter.

Key Differences
Neutrons are subatomic particles found in the nucleus of an atom, crucial for the stability of most atoms by contributing to the strong nuclear force. Neutrinos, on the other hand, are elusive particles that rarely interact with matter and are not part of the atom's structure.
While neutrons have a significant mass about the same as that of protons, neutrinos are almost massless. This stark difference in mass affects how they are detected and studied.
Neutrons are involved in nuclear reactions, such as fission and fusion, where they can initiate and sustain chain reactions. Neutrinos, however, are typically byproducts of nuclear reactions, with no role in initiating or sustaining these reactions.
In terms of detection, neutrons can be detected through their interaction with other atomic nuclei, leading to observable secondary particles. Neutrinos, on the other hand, are much more challenging to detect due to their weak interaction with matter, requiring massive and sensitive detectors.
Finally, the study of neutrons helps in understanding nuclear physics and atomic structure, whereas neutrinos are studied primarily in the context of astrophysical processes and fundamental particle physics.

Compare with Definitions
Neutron
A subatomic particle with no electrical charge, found in the nucleus of an atom.
Neutrons play a key role in the stability of an atom.
Neutrino
An elementary particle with very low mass and no charge, interacting only through the weak force.
Neutrinos are often emitted in beta decay.
Neutron
Neutron beams are used in scientific research to study material structures.
Neutron scattering techniques help reveal the arrangements of atoms in a crystal.
Neutrino
Neutrinos pass through most matter unimpeded and undetected.
Trillions of neutrinos pass through your body every second without any interaction.
Neutron
Neutrons contribute to the atomic mass but do not influence the electrical properties.
The neutron's lack of charge allows it to penetrate materials easily.
Neutrino
Neutrinos come in three types or 'flavors': electron, muon, and tau neutrinos.
Neutrino flavor oscillation is a phenomenon observed in these particles.
Neutron
Neutrons are a type of baryon, composed of three quarks.
The quark composition gives neutrons their mass and force interactions.
Neutrino
Produced abundantly in nuclear reactions in stars, including our sun.
Neutrinos from the sun help us study solar processes.
Neutron
In nuclear reactions, neutrons can induce fission when absorbed by a nucleus.
Neutron absorption is critical in nuclear reactors.
Neutrino
Due to their minimal interaction, neutrinos are difficult to detect, requiring large underground detectors.
The detection of neutrinos requires sophisticated technology like that used in the IceCube observatory.
Neutron
The neutron is a subatomic particle, symbol n or n0, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Neutrino
A neutrino ( or ) (denoted by the Greek letter ν) is a fermion (an elementary particle with spin of 1/2) that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero.
Neutron
The electrically neutral nucleon, a baryon composed of two down quarks and one up quark, which has a mass 1,839 times that of an electron, is stable when bound in an atomic nucleus, but has a mean lifetime of 886 seconds as a free particle. It is a basic component of all atomic nuclei except the protium isotope of hydrogen.
Neutrino
Any of three electrically neutral leptons (the electron neutrino, muon neutrino, and tau neutrino—one in each of the three generations of elementary fermions) that have very small masses.
Neutron
(particle) A subatomic particle forming part of the nucleus of an atom and having no charge; it is a combination of an up quark and two down quarks.
Neutrino
An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect.
Neutron
An elementary particle with 0 charge and mass about equal to a proton; enters into the structure of the atomic nucleus
Neutrino
An elementary particle with zero charge and zero mass
