  • The nuclei of atoms are made from protons and, except for ordinary hydrogen, neutrons.. Neutrons and protrons are compound particles composed of three quarks each held together with the colour fource. Neutrons are held in the nucleus by the strong nuclear force, a residual effect left over from the colour force. Neutrons and protons also have spin 1/2. In a nuclear bomb, a neutron enters a Uranium-235 nucleus which splits and releases more neutrons to make a chain reaction. A neutrino is an elementary particle. It has spin 1/2 and no charge. It's existence was guessed because it is needed to make spin equations balance in weak nuclear reactions. It is now known to have some very small mass rather than zero as once believed. Neutrinos travel at a shade slower than the speed of light. Neutrinos are weakly interacting, and of those generated in the nuclear reactions in the sun most of those that reach the earth will pass straight through. So apart from spin and charge, these particles are very different! The neutrino is elementary, almost massless, generated in a nuclear reactions and very difficult to detect. The neutron is non-elementary and a common particle which makes up a sizeable part of the mass of most substances including you!
