Alpha Particle Emission
A type of radioactive decay in which an atomic nucleus releases an alpha particle (2 protons and 2 neutrons) and transforms into an atom with a mass number 4 units less and atomic number 2 units less.
Beta Particle Emission
A radioactive decay process where a beta particle (electron or positron) is emitted from an atomic nucleus.
Alpha Particle Emission
A type of radioactive decay in which an unstable atomic nucleus emits an alpha particle (2 protons and 2 neutrons) to form a new nucleus, decreasing its atomic number by 2 and mass number by 4.
Positron Particle Emission
A type of beta decay in which a positron is ejected from an atomic nucleus, transforming a proton into a neutron.
