In beta decay, allowed transitions follow conservation laws for energy, momentum, and angular momentum, while forbidden transitions violate these laws. Allowed transitions result in the emission of beta particles with specific energies and momenta. Forbidden transitions are rare and involve higher-order interactions, resulting in beta particles with nonstandard energies or angular momenta.
The energy of beta particles in beta decay is not fixed because it depends on the specific isotope and decay process involved. Beta decay can produce high-energy electrons and positrons through beta minus and beta plus decay, respectively. The energy of the beta particles is determined by the energy released during the decay process.
Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).
There is a difference between beta emitters and beta particles. In situations where an atomic nucleus exhibits nuclear instability due to too many neutrons for the number of protons or vice versa, that nucleus may undergo beta decay. It the decay event occurs, that atom is considered a beta emitter. The emitted particle is the beta particle. That's the difference. (There are two different beta particles, so check the articles on beta decay to get the scoop.)
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
Beta decay involves the release of electrons (beta particles) or positrons, along with neutrinos. Beta decay occurs when a neutron changes into a proton within an atomic nucleus, which leads to the emission of a beta particle.

There are two types of beta decay, and they are beta plus (beta +) decay and beta minus (beta -) decay. A post already exists on beta decay, and a link to that related question can be found below.

Beta decay is a property of atoms not molecules.
During beta decay, a beta particle (an electron or positron) is emitted, along with an antineutrino or neutrino, depending on whether it's beta-minus or beta-plus decay, respectively. Beta decay involves the transmutation of a neutron into a proton within the nucleus, releasing the beta particle in the process.

From weakest to strongest decay, the order is: Gamma decay - involves the emission of high-energy photons. Beta decay - involves the emission of beta particles (electrons or positrons). Alpha decay - involves the emission of alpha particles (helium nuclei).
During beta decay, a beta particle (either an electron or a positron) is emitted from the nucleus of an atom. This emission occurs when a neutron in the nucleus is transformed into a proton, with the accompanying release of a beta particle and an antineutrino (in the case of beta-minus decay) or a neutrino (in the case of beta-plus decay).
It does not usually involve the atom's electrons, except for a type of decay called K capture. But the beta particles ejected in what is called beta decay are either electrons or positrons.
