When one speaks of isotopes, they are referring to the set of nuclides that have the same number of protons. Mass Spectroscopy Mass Spectroscopy is a technique causing the formation of the gaseous ions with or without fragmentation; the gas phase ions are then characterized by their mass to charge ratios (m/z) and their relative abundances. For example, carbon-14 can be described in two ways:. Only three isotopes are considered significant enough to have names of their own, as opposed to being named after a parent atom (for example, carbon-12, uranium-238).
