These are found in the centre of the atom and have no charge (i.e. It is neutral). If this number varies in a certain element you get an isotope of the element. For example, carbon-dating uses an isotope of carbon to put an age on very old artefacts found.
The neutral particles in the Nucleus of an atom.
Uncharged particles found in the nucleus of an atom which contribute to the total weight of the atom.
Has no electrical charge and is approximately the same mass as a proton. Located in the nucleus of an atom. Neutron radiation is produced during the fission process.
Uncharged particles that are found in the nucleus of an atom.
Neutrally charged particles (an oxymoron.)
Neutron particles are released following fission of uranium and plutonium. Neutrons penetrate deeply into tissue but do not carry an electrical charge. When a neutron strikes a nucleus it may merely bounce off or it may be absorbed into the nucleus causing a change in the nature of the nucleus.
Uncharged sub-atomic particles with a mass of 1 relative to a proton. Radioactivity
One of the two types of particle which form the nucleus of an atom—the other being the proton.
An uncharged elementary particle that has a mass nearly equal to that of the proton and is present in atomic nuclei.
