A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction.They are used for commercial electricity, marine propulsion, weapons production and research.
A model of an atomic nucleus showing it as a compact bundle of protons (red) and neutrons (blue), the two types of nucleons.In this diagram, protons and neutrons look like little balls stuck together, but an actual nucleus (as understood by modern nuclear physics) cannot be explained like this, but only by using quantum mechanics.
The neutron is a subatomic particle, symbol n or n 0, that has no electric charge, and a mass slightly greater than that of a proton.Protons and neutrons constitute the nuclei of atoms.
