WebJust as isotopes are the result of changes in the number of neutrons, ions—atoms that are either positive or negative in electric charge—are the result of changes in the number of electrons. Unless it loses or gains an electron, thus becoming an ion, an atom is neutral in charge, and it maintains this electric-charge neutrality by having an ... WebMolybdenum-92 and molybdenum-100 are the only naturally occurring isotopes which are not stable. Molybdenum-100 has a half-life of approximately 1×10 19 y and undergoes double beta decay into ruthenium-100.Molybdenum-98 is the most common isotope, comprising 24.14% of all molybdenum.
