WebMass numbers of typical isotopes of Phosphorus are 31. Main 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. … WebThe quantities of phosphorus leached or carried away by erosion are always low in comparison with the quantity of P taken by plants. Therefore, without P application, dynamics of P in soil-plant systems depends mainly on plant P uptake from available soil P. This paper concerns mainly the description and the analysis of available soil phosphate.

The early history of 32P as a radioactive tracer in biochemical

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 Webphosphorus-32: n.
