There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium (hydrogen-3): if the atom loses one or more electrons, it becomes a positively-charged ion if the atom gains one ...

The Facility for Rare Isotope Beams ... which removes the atom's electrons, creating a positively charged ion. Those ions are then guided into the linear accelerator, where they are moved through ...

As a result, concentrations down to one atom in 1017 atoms are measurable ... analyzers are used to measure the abundance of a rare isotope, 14C in this case. Negative carbon ions are drawn from a ...
