WebNuclear chemistry. Alpha decay is one type of radioactive decay, in which an atomic nucleus emits an alpha particle, and thereby transforms (or "decays") into an atom with a mass number decreased by 4 and atomic number decreased by 2. Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and ... Web9 apr. 2024 · Nuclear chemistry is a sub-discipline of chemistry dealing with the study of changes in the nucleus of atoms of elements. These nuclear changes are a source of nuclear power and radioactivity, and the energy released from the nuclear reactions has far-reaching applications.
