Web33 P is a beta-emitter (0.25 MeV) with a half-life of 25.4 days. It is used in life-science laboratories in applications in which lower energy beta emissions are advantageous such as DNA sequencing. 33 P can be used to label nucleotides. It is less energetic than 32 P, giving a better resolution.

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 ... WebWhite phosphorus, P4, spontaneously bursts into flame in oxygen. if 6.5g of white phosphorus reacts with sufficient oxygen to form 11.54g of a phosphorus oxide, what is the empirical formula of this oxide? Suppose that a device is using a 5.00-mg sample of silicon that is doped with 1 × 10-5% (by mass) phosphorus.
