{{Short description|Field of physics that studies atomic interactions}} {{About|the study of atomic nuclei}} {{Nuclear physics}} '''Nuclear physics''' is the field of [[physics]] that studies [[atomic nuclei]] and their constituents and interactions, in addition to the study of other forms of [[nuclear matter]]. Nuclear physics should not be confused with [[atomic physics]], which studies the [[atom]] as a whole, including its [[electron]]s. Discoveries in nuclear physics have led to [[nuclear technology|applications]] in many fields such as [[nuclear power]], [[nuclear weapons]], [[nuclear medicine]] and [[magnetic resonance imaging]], industrial and agricultural isotopes, [[ion implantation]] in [[materials engineering]], and [[radiocarbon dating]] in [[geology]] and [[archaeology]]. Such applications are studied in the field of [[nuclear engineering]]. [[Particle physics]] evolved out of nuclear physics and the two fields are typically taught in close association. [[Nuclear astrophysics]], the application of nuclear physics to [[astrophysics]], is crucial in explaining the inner workings of [[stars]] and the [[nucleosynthesis|origin of the chemical elements]].
