Usually when isotopes undergo beta decay they emit an electron, but some isotopes emit a positron instead. This depends on the relative number of neutrons to protons in the isotope which type of beta particle is emitted. An excess of neutrons leads to the emission of an electron, while an excess of protons leads to the emission of a positron.
A beta particle is produced in a process called beta decay, in which a neutron becomes a proton or vise versa. There are two forms of beta decay:normal beta decay - a neutron becomes a proton, a beta particle (i.e. electron) and an antineutrinoantibeta decay - a proton becomes a neutron, an antibeta particle (i.e. positron) and a neutrino
Product of radioactive decay 42He is an alpha particle
The equation for the beta decay of 24Na is: 1124Na --> 1224Mg + -10e where the e is a negative beta particle or electron.

When 60Co decays by beta- decay it produces 60Ni.
When tritium-3 emits a beta particle, it becomes helium-3. The beta particle is an electron, so when it is emitted, a neutron in the tritium nucleus is converted into a proton, resulting in helium-3, which has two protons and one neutron.
The isotope formed when tritium (3H) emits a beta particle is helium-3 (3He). This process occurs when a neutron in the tritium nucleus converts to a proton, releasing a beta particle (electron) and an electron antineutrino.
An example of beta decay for a thorium isotope: Th-231(beta)Pa-231.
Beta particle
transformation of a neutron into a proton, an electron (beta particle), and an antineutrino. This process is known as beta decay and occurs in isotopes with an excess of neutrons compared to protons, seeking to attain a more stable ratio of protons to neutrons.
With the ejection of a beta particle (electron), there is a minute loss of mass. Electrons have very low mass. The atomic number increases though as a neutron is transformed into a proton. A antineutrino is also ejected. In a similar process, positron emission also called beta decay,- a positron is emitted and a proton is transformed into a neutron, the atomic number decreases. A neutrino is also ejected.
The isotopes Cm-249, Cm-251 and Cm-252 are transformed by beta decay in the isotopes Bk-249, Bk-251 and Bk-252.
The isotopes Cm-249, Cm-251 and Cm-252 are transformed by beta decay in the isotopes Bk-249, Bk-251 and Bk-252.
Beta particle( electron having nuclear origin) is emitted when a neutron decays into a proton by giving out electron. The electron produced escapes as a beta particle leaving proton in the nucleus of atom. 0n1 --> 1p1 + -1e0 ( 1e0 is the emitted beta particle) here subscripts denote charge and superscript denote mass in atomic mass unit(amu). Such neutron decay are shown by some radioactive elements. Usually when the n/p (neutron/proton) ratio is higher than required nuclei emit beta particle. Many examples of this type of decay can be given like: 6c14 --> 7N14 + -1e0 (this carbon isotope is used in carbon dating). 90Th232 + 0n1 --> 90Th232 - -1e0 --> 91Pa233 - -1e0 --> 92U233 (this reaction is used in breeder reactors for production of fissile uranium isotope)
The isotope curium 244 is obtained by nuclear reactions between plutonium and neutrons. The decay of Cm 244 is by alpha disintegration, not beta.
When 90Sr undergoes beta decay, it forms 90Y (Yttrium-90). In beta decay, a neutron is converted into a proton, and an electron (beta particle) and an antineutrino are emitted.
