Singleionization
Single ionization is a process in atomic and molecular physics where an atom or molecule loses exactly one electron. This results in the formation of a positively charged ion, also known as a singly charged cation. The energy required to remove this electron from a neutral atom or molecule is called the first ionization energy. This energy is a fundamental property of each element and is influenced by factors such as the nuclear charge and the electron shielding effect.
Single ionization can occur through various mechanisms. Photoionization, for example, happens when an atom or molecule
The extent to which single ionization occurs depends on the incident energy and the type of particle
