Livermorium-292

Properties and data of the isotope ²⁹²Lv.

Content

Livermorium-292 is a radioisotope of the chemical element livermorium, which, in addition to the element-specific 116 protons, has 176 neutrons in the atomic nucleus, resulting in the mass number 292. The very short-lived, only artificially producible, unstable and therefore radioactive nuclide has no practical significance; dealing with ²⁹²Lv is for academic purposes only.
