Ionization's the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions. This's often confused with dissociation (chemistry). The process works slightly differently depending on whether an ion with a positive or a negative electric charge's being produced. A positively charged ion's produced when an electron bonded to an atom (or molecule) absorbs enough energy to escape from the electric potential barrier that orig… (More on Ionized)
