Atomic and Nuclear Physics
Atomic and Nuclear Physics Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus . It is primarily concerned with the arrangement of electrons around the nucleus and the processes by which these arrangements change. This includes ions as well as neutral atoms and, unless otherwise stated, for the purposes of this discussion it should be assumed that the term atom includes ions. Atomic physics also helps to understand the physics of molecules, but there is also molecular physics, which describes the physical properties of molecules. Nuclear physics is the field of physics that studies the constituents(protons and neutrons) and interactions of atomic nuclei. The most commonly known applications of nuclear physics are nuclear power generation, but modern nuclear physics contains also particle physics, which is taught in close association with nuclear physics. The nuclear physics has provided application in many fields, inclu
