Neutron is a sub atomic particle, which resides in the nucleus of an atom. It is denoted by n. Neutron does not have a charge. Its mass is 1.674927 X 10^?27 kg, which is slightly higher than the mass of a proton.

 Neutrino is a sub atomic particle with a small mass (similar to electrons) and no electrical charge. Since there is no electrical charge, neutrinos are not affected by the electrical or magnetic forces. It is shown by the letter ? (nu). Three types of neutrinos have been described as electron neutrino, muon neutrino and tau neutrino. Neutrino has a spin of half integer. It is hard to determine neutrinos directly as they don’t carry a charge, and don’t ionize the materials they are passing through.
