Monoisotopic element

Term · Chemistry · MLC-T-CHM-007546

An element that has only one stable, naturally occurring isotope. As a result, its standard atomic weight is determined directly from the mass of this single nuclide and is known with very high precision. There are 26 such elements, including beryllium, fluorine, sodium, aluminum, and gold.
