Beta Particle vs. Electron: What's the Difference?
A beta particle is a high-energy, high-speed electron or positron emitted during radioactive decay, while an electron is a stable subatomic particle with a negative charge found in all atoms.
Beta particles are emitted from an unstable nucleus during radioactive decay, carrying a charge of either minus (beta minus decay) or plus (beta plus decay). Electrons are stable, negatively charged particles present in the outer shells of atoms, crucial for chemical bonding.
While beta particles are a product of a nuclear reaction and can be either electrons or positrons, electrons are fundamental components of atoms and always carry a negative charge.
Beta particles have high energy and speed when emitted, capable of penetrating materials and causing ionization. Electrons, in their normal atomic state, have lower energies and are bound to the nucleus by electromagnetic force.
In beta minus decay, a neutron transforms into a proton and emits a beta particle (electron) and an antineutrino. Electrons, however, do not transform into other particles under normal conditions.
The study of beta particles is essential in understanding radioactive decay and nuclear physics, whereas electrons are fundamental to the study of chemistry, electricity, and general physics.

Beta particles have sufficient energy to ionize atoms and molecules.
An elementary particle with a role in forming atoms and molecules.
The sharing or transfer of electrons leads to the formation of chemical bonds.
A charged particle produced during the transformation of a neutron into a proton.
The detection of beta particles helps in understanding the decay process of radioactive elements.
A stable, negatively charged subatomic particle in the electron shell of an atom.

The number of electrons in an atom determines its chemical properties.
An energetic subatomic particle ejected from a radioactive nucleus.
In beta decay, beta particles are released from the nucleus of an atom.
A fundamental particle responsible for electricity and chemical bonding.
The flow of electrons in a conductor constitutes an electric current.
A particle involved in beta decay, either as an electron or a positron.
Beta particles are used in medical treatments and scientific research.
A particle with a negative charge, playing a key role in electricity and magnetism.
Electrons in magnetic fields exhibit a deflection due to their charge.
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.
(particle) The subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity.
Alloys of magnesium and other metals, like aluminum or zinc, that were manufactured by the German company Chemische Fabrik Griesheim-Elektron.
Amber; also, the alloy of gold and silver, called electrum.
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
