The neutron is a subatomic particle, symbol n or n0 , with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Protons are positively charged sub atomic particles with a mass of about 1 amu.Neutrons are neutral sub atomic particles with a mass of 1 amu. Electrons are negatively charge â¦ d sub atomic particles with a mass 1837 times less than that of the protons.
