WebTo put it simply, positive ions are molecules that have lost one or more electrons whereas negative ions are actually oxygen atoms with extra-negatively-charged electrons. Negative ions are abundant in nature, especially around waterfalls, on the ocean surf, at the beach and widespread in mountains and forests. They neutralize free radicals. WebFORMATION OF IONS: Ionization is the phenomenon of a neutral atom shedding or acquiring electrons, resulting in ions' formation. Ions are formed when the number of protons in an atom does not equal the number of electrons. An ion therefore is an atom that has gained or lost one or more electrons and therefore has a negative or positive charge.
