Definition of Neutron The neutron is the particle in the atomic nucleus with a mass = 1 and charge = 0. Neutrons are found together with protons in the atomic nucleus. The number of neutrons in an atom determines its isotope. Although a neutron has a net neutral electrical charge, it does consist of charged … Read more
Definition of Proton Proton is a stable subatomic particle with a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10-27 kg, which is 1,836 times the mass of an electron. Every nucleus of a given chemical element has the same number of protons. This number … Read more
Definition of Electron An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron. … Read more
