The alpha decay reduces the atomic number of the nucleus by 2 and the mass number by 4: Beta rays are more penetrating than alpha rays, move at a very high speed, and are deflected considerably by a magnetic field in a direction that indicates a negative charge; analysis shows that beta rays are high-speed electrons (see beta particlebeta particle,one of the three types of radiation resulting from natural radioactivity.

Beta radiation (or beta rays) was identified and named by E.

The disintegration proceeds at a definite rate characteristic of the particular nucleus; that is, each radioactive isotoperadioactive isotopeor radioisotope,natural or artificially created isotope of a chemical element having an unstable nucleus that decays, emitting alpha, beta, or gamma rays until stability is reached...... However, the time of decay of an individual nucleus is unpredictable.Alpha rays are nuclei of ordinary helium atoms (see alpha particlealpha particle,one of the three types of radiation resulting from natural radioactivity.Alpha radiation (or alpha rays) was distinguished and named by E. Rutherford in 1909, who found by measuring the charge and mass of alpha particles that they are the nuclei of ordinary..... Alpha decay reduces the atomic weight, or mass number, of a nucleus, while beta and gamma decay leave the mass number unchanged.neutrino[Ital.,=little neutral (particle)], elementary particle with no electric charge and a very small mass emitted during the decay of certain other particles.The neutrino was first postulated in 1930 by Wolfgang Pauli in order to maintain the law of conservation of energy..... The electron is immediately ejected from the nucleus, and the net result is an increase of 1 in the atomic number of the nucleus but no change in the mass number.Other, less common, types of radioactivity are electron capture (capture of one of the orbiting atomic electrons by the unstable nucleus) and positron emission—both forms of beta decay and both resulting in the change of a proton to a neutron within the nucleus—an internal conversion, in which an excited nucleus transfers energy directly to one of the atom's orbiting electrons and ejects it from the atom.
