More Chemistry
Phosphorus-30 is a radioisotope of the chemical element Phosphorus, which, in addition to the element-specific 15 protons, has 15 neutrons in the atomic nucleus, resulting in the mass number 30. The very short-lived, unstable and therefore radioactive nuclide, which can only be produced artificially, has no practical significance; The study of 30P is exclusively for academic purposes.
The discovery of this isotope, which does not occur in nature, by Irène Joliot-Curie and Frédéric Joliot and their findings on the synthesis of new radioactive elements was honored with the Nobel Prize in Chemistry in 1935.

Phosphorus-30 is a positron emitter that radioactively decays into silicon-30.
Half-life T½ = 2.498(4) min (minutes) respectively 1.4988 × 102 seconds s.
