Beta Particle vs. Electron — What's the Difference?
By Tayyaba Rehman — Published on December 11, 2023
A Beta Particle is a high-energy, high-speed electron or positron emitted in radioactive decay, while an Electron is a stable subatomic particle with a negative charge.

Key Differences
Beta Particles and Electrons are subatomic entities, but their contexts of emergence and characterization are distinct. While both have charge and mass, the conditions under which they exist and function differ widely.
A Beta Particle is emitted during the radioactive decay of certain unstable atomic nuclei. When a neutron in a nucleus transforms into a proton, a Beta Particle (electron) is released. Conversely, an Electron is a fundamental component of atoms, orbiting the nucleus and contributing to the atom's chemical properties.
The energy of a Beta Particle varies because it arises from a dynamic decay process. This contrasts with Electrons which, when in atomic orbitals, have fixed energy levels. However, when freed from atoms, Electrons can gain or lose energy, such as in electrical currents.
It's essential to recognize that while all Beta Particles are Electrons (or positrons), not all Electrons are Beta Particles. Beta Particles specifically refer to Electrons (or positrons) from nuclear decay, differentiating them from atomic Electrons.
Technologically, both Beta Particles and Electrons have wide applications. Beta Particle emissions are used in various medical and industrial processes, while Electrons play a pivotal role in electronics, electricity, and chemical bonding.

Compare with Definitions
Beta Particle
Beta Particle can be an electron or positron.
Beta-minus decay results in the emission of a Beta Particle in the form of an electron.
Electron
Electron is fundamental in electricity.
Electric current is essentially the flow of Electrons.
Beta Particle
Beta Particle is a product of radioactive decay.
Tritium decays and releases a Beta Particle.
Electron
Electron is a negatively charged subatomic particle.
An atom's outer Electron defines its chemical reactivity.
Beta Particle
Beta Particle has high energy and speed.
Due to its energy, a Beta Particle can penetrate materials but is stopped by plastic or glass.
Electron
Electron orbits the atomic nucleus.
The distribution of Electrons around a nucleus determines an element's place in the periodic table.
Beta Particle
Beta Particle can ionize atoms.
In Geiger counters, the ionization caused by a Beta Particle is detected.
Electron
Electron participates in chemical bonding.
In a covalent bond, two atoms share their Electrons.
Beta Particle
Beta Particle changes the atomic number of the nucleus.
The release of a Beta Particle can convert a neutron to a proton.
Electron
Electron has a fixed charge and mass.
The charge of an Electron is approximately -1.6 x 10^-19 Coulombs.
Electron
A stable elementary particle in the lepton class having a negative electric charge of 1 elementary unit (about 1.602 × 10-19 coulombs) and a mass of about 9.11 × 10-28 grams. Electrons are found in shells orbiting the nuclei of atoms and can also move freely through space as cathode rays in a cathode-ray tube or as beta particles emitted by radioactive nuclei, or flow in a current through a conducting material impelled by an electric potential difference.
Electron
(particle) The subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity.
Electron
Alloys of magnesium and other metals, like aluminum or zinc, that were manufactured by the German company Chemische Fabrik Griesheim-Elektron.
Electron
Amber; also, the alloy of gold and silver, called electrum.
Electron
One of the fundamental subatomic particles, having a negative charge and about one thousandth the mass of a hydrogen atom. The electron carries (or is) a natural unit of negative electricity, equal to 3.4 x 10-10 electrostatic units, and is classed by physicists as a lepton. Its mass is practically constant at the lesser speeds, but increases due to relativistic effects as the velocity approaches that of light. Electrons are all of one kind, so far as is known. Thus far, no structure has been detected within an electron, and it is probably one of the ultimate composite constituents of all matter. An atom or group of atoms from which an electron has been detached has a positive charge and is called a cation. Electrons are projected from the cathode of vacuum tubes (including television picture tubes) as cathode rays and from radioactive substances as the beta rays. Previously also referred to as corpuscle, an obsolete term. The motion of electrons through metallic conductors is observed as an electric current. A particle identical to the electron in mass and most other respects, but having a positive instead of a negative charge, is called a positron, or antielectron
