College Physics I – Introduction
Ionization is the process by which an atom or molecule gains or loses electrons, resulting in the formation of charged particles known as ions. This phenomenon is significant in various contexts, as it is essential for understanding how energy from photons can interact with matter, leading to changes in atomic and molecular structure. Additionally, ionization plays a crucial role in nuclear reactions and radioactivity, where unstable nuclei emit radiation that can cause ionization in surrounding materials.
