👉 In physics and chemistry, a photoionization is an atomic process that involves the emission of electrons from a charged particle. The process can be characterized by two key steps:
1.
Electron Release
: This occurs when a positively charged particle (e.g., electron) excites an electron in another atom to release a photon (a short-wavelength electromagnetic radiation).
2.
Ionization
: In the ionization step, an excited electron is ejected from the original atom and becomes a positively charged
