Phosphore isotope
Webisotope is given for elements without a stable nuclide. Nuclides marked with an asterisk (*) in the abundance column indicate that it is not present in nature or that a meaningful natural abundance cannot be given. The isotopic mass data is from G. Audi, A. H. Wapstra Nucl. Phys A . 1993, 565 , 1-65 and G. Audi, A. H. Wapstra Nucl. Phys A . 1995, Although phosphorus (15P) has 22 isotopes from P to P, only P is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are P with a half-life of 25.34 days and P with a half-life of 14.268 days. All others have half-lives of under 2.5 minutes, most under a second. … See more Phosphorus-32 P, a beta-emitter (1.71 MeV) with a half-life of 14.3 days, is used routinely in life-science laboratories, primarily to produce radiolabeled DNA and RNA probes, e.g. for use in See more • Phosphorus isotopes data from The Berkeley Laboratory Isotopes Project's See more
