what is the difference between a neutron and a nucleus
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 â27 kg, which is slightly higher than the mass of a proton.A nucleus of an atom also contains protons, which are positively charged.If there are only protons in the nuclei, the repulsion between those will be higher. Therefore, presence of neutrons is important to bind the protons together in the nuclei. Single element can have different number of neutrons in their nuclei.eutron does not have a charge.
