Neutron is one of the components that make up the structure of an atom along with the protons and electrons. It is a subatomic particle that has no electric charge and its mass i.e., 1.67493 × 10−27 kg is slightly greater than that of the proton. The electrons around the nucleus in the orbitals whereas the protons and the neutrons exist inside the nucleus.
Due to their existence in the nucleus, they are termed as nucleons. The nucleons are known to occupy 99.9% of the atoms’ total mass. The recent advancements have revealed that the neutrons are composed of small particles named quarks. The total number of neutrons and protons in an atom defines the mass number of the element.
