WebMain Isotopes of Phosphorus. 23 isotopes of phosphorus are known, ranging from 25P to 47P. Only 31P is stable and is therefore present at 100% abundance. Phosphorus-31 is composed of 15 protons, 16 neutrons, and 15 electrons. The half-integer nuclear spin and high abundance of 31P make phosphorus-31 NMR spectroscopy a very useful analytical ...
