'''Ionization''' is the process by which a neutral atom or molecule acquires a positive or negative electrical charge by gaining or losing electrons. It is the foundational step in [[mass spectrometry]], plasma physics, and atmospheric chemistry, transforming neutral matter into charged species that can be manipulated by electric and magnetic fields.\n\nThe physical mechanisms of ionization span a wide range of energies and environments. Electron impact ionization, the classical method, uses high-energy electrons to knock valence electrons from molecules. Electrospray ionization, developed by John Fenn in 1984, produces ions from solution-phase molecules and revolutionized the analysis of large biomolecules. Matrix-assisted laser desorption ionization (MALDI) uses laser energy absorbed by a matrix to vaporize and ionize large, fragile molecules without fragmentation.\n\nEach ionization method produces a characteristic fragmentation pattern that encodes structural information about the parent molecule. The pattern is not arbitrary; it reflects the molecular topology, bond strengths, and energetics of the ionization process. Understanding fragmentation is therefore a problem of inverse inference: given the observed ion distribution, what molecular structure produced it?\n\n[[Category:Chemistry]]\n[[Category:Physics]]\n[[Category:Technology]]
