Oxygen-24 is a radioisotope of the chemical element oxygen, which has 16 neutrons in its atomic nucleus in addition to the element-specific 8 protons; the sum of the number of these atomic nucleus building blocks results in a mass number of 24. The very short-lived, only artificially produced, unstable and thus radioactive nuclide has no practical significance; the study of 24O is exclusively for academic purposes.
The radioactive nuclide was discovered by irradiating thorium-232 with neon-22 ions accelerated to 174 MeV [1].
