Isotopes of phosphorus
Although phosphorus (P) has multiple isotopes, only one of these isotopes is stable 31P; as such, it is considered a monoisotopic element. Standard atomic mass: 30.973762(2) u. Radioactive isotopes of phosphorus include: 32P; a beta-emitter (1.71 MeV) with a half-life of 14.3 days which is used routinely in life-science laboratories, primarily to produce radiolabeled DNA and RNA probes, e.g. for use in Northern blots or Southern blots. Because the high energy beta particles produced penetrate skin and Six radioactive isotopes of phosphorus are known also. A radioactive isotope is one that breaks apart and gives off some form of radiation. Radioactive isotopes are produced when very small particles are fired at atoms. These particles stick in the atoms and make them radioactive. One radioactive isotope, phosphorus-32, has applications in medicine, industry, and tracer studies. A tracer is a radioactive isotope whose presence in a system can easily be detected. The isotope is injected into the system where it gives off radiation. Although phosphorus (15P) has 24 isotopes from 24P to 47P. Only one of these isotopes, 31P, is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are 33P with a half-life of 25.34 days and 32P with a half-life of 14.263 days. All others have lived under 2.5 minutes, most under a second. The least stable is 25P with a half-life shorter than 30 nanoseconds⠔the half-life of 24P is unknown. Contents. 1 Radioactive isotopes. 1.1 Phosphorus-32. 1.2 Phosphorus-33. Although phosphorus (15P) has 24 isotopes from 24P to 47P, only 31P, is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are 33P with a half-life of 25.34 days and 32P with a half-life of 14.263 days. All others have lived under 2.5 minutes, most under a second. The least stable is 25P with a half-life shorter than 30 nanoseconds⠔the half-life of 24P is unknown. 6 Isotopes. 7 Applications. 8 Biological role. Red phosphorus may be formed by heating white phosphorus to 250°C (482°F) or by exposing white phosphorus to sunlight. Phosphorus after this treatment exists as an amorphous network of atoms which reduces strain and gives greater stability, further heating results in the red phosphorus becoming crystalline. Red phosphorus does not catch fire in air at temperatures below 240°C, whereas white phosphorus ignites at about 40°C. Meaning of Isotopes of phosphorus medical term. What does Isotopes of phosphorus mean? a radioisotope of phosphorus having a half- life of 14.3 days and emitting only beta rays; used in the form of sodium phosphate P-32 for treatment of polycythemia vera, chronic myelocytic leukemia and chronic lymphocytic leukemia, and in localizing certain tumors during surgery.
