Lithium-10

Properties and data of the isotope ¹⁰Li.

Content

Lithium-10 is a radioisotope of the chemical element Lithium, which, in addition to the element-specific 3 protons, has 7 neutrons in the atomic nucleus, resulting in the mass number 10. The very short-lived, unstable and therefore radioactive nuclide, which can only be produced artificially, has no practical significance; The study of ¹⁰Li is for academic purposes only.
