neutron

A neutron is a subatomic particle found in the nucleus of an atom, alongside protons. Unlike protons, which have a positive charge, neutrons are electrically neutral, meaning they have no charge. They play a crucial role in the stability of an atom; they help bind protons together to form the nucleus through the strong nuclear force. The number of neutrons, along with protons, determines the type of element and its isotopes. Neutrons are essential for nuclear reactions and are key in processes like fission, which powers nuclear reactors and atomic bombs.
