Oxygen-27 is a radioisotope of the chemical element oxygen, which has 19 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 27. The very short-lived, only artificially produced, unstable and thus radioactive nuclide has no practical significance; the study of 27O is exclusively for academic purposes.
The following data are preliminary and calculated based on theoretical considerations.
