Answer and Explanation: The part of an atom in which alpha or beta particles originate in the nucleus. Beta particles are characterized as negatively charged particles.
Alpha, beta and gamma decay are a result of the three fundamental forces working in the nucleus – the 'strong' force, the 'weak' force and the 'electromagnetic' force. In all three cases, the emission of radiation increases the nucleus stability, by adjusting its proton/neutron ratio.
An alpha particle is made up of two protons and two neutrons bound together. Beta particles are high energy electrons. Gamma rays are waves of electromagnetic energy, or photons.
Alpha radiation consists of helium nuclei and is readily stopped by a sheet of paper. Beta radiation, consisting of electrons or positrons, is stopped by a thin aluminum plate, but gamma radiation requires shielding by dense material such as lead or concrete.
What causes some radionuclides to emit beta particles? Beta minus particle (β-) emission occurs when the ratio of neutrons to protons in the nucleus is too high. An excess neutron transforms into a proton and an electron. The proton stays in the nucleus and the electron is ejected energetically.
Alpha particles (α) are positively charged and made up of two protons and two neutrons from the atom's nucleus. Alpha particles come from the decay of the heaviest radioactive elements, such as uranium, radium and polonium.Jul 13, 2021
The beta particle, which may be either negatively charged (negatrons) or positively charged (positrons), originates from the nucleus of an atom. A beta particle is emitted from the nucleus of an atom during radioactive decay. The electron, however, occupies regions outside the nucleus of an atom.
An alpha particle is produced by the alpha decay of a radioactive nucleus. Because the nucleus is unstable a piece of it is ejected, allowing the nucleus to reach a more stable state.
beta particle, electron (unit negative charge) or positron (unit positive charge) spontaneously emitted by certain unstable atomic nuclei in the radioactive disintegration process of beta decay (q.v.).Mar 17, 2022
If the count rate is not significantly reduced, place a 2 mm thick sheet of aluminum between the source and the monitor. If the count rate goes almost to the background level, the source is emitting beta particles. If the count rate is only reduced, the source is a gamma source.
Definition of beta particle : a high-speed electron specifically : one emitted by a radioactive nucleus in beta decay.
