A neutron.
Alpha particles are more highly charged than beta particles, as they consist of two protons and two neutrons, giving them a charge of +2. Beta particles, on the other hand, are either electrons (β-) or positrons (β+), which have a charge of -1 and +1, respectively.
This elementary particle is the electron.
An elementary particle carrying a unit charge of negative electricity is called an electron.
An electron
The electron was the first elementary particle to be discovered in 1897 by J.J. Thomson. It is a fundamental constituent of matter and carries a negative electric charge.
A neutron is an elementary particle found in the nucleus of an atom, carrying no electric charge.
Electron carries negative charge. Electron is an elementary particle.
