The longest-lived radioisotope of lithium is 8 Li, which has a half-life of just 838.7(3) milliseconds. 9 Li has a half-life of 178.2(4) ms, and 11 Li has a half-life of 8.75(6) ms. All of the remaining isotopes of lithium have half-lives that are shorter than 10 nanoseconds.

Lithium-8 is a radioisotope of the chemical element Lithium, which, in addition to the element-specific 3 protons, has 5 neutrons in the atomic nucleus, resulting in the mass number 8.

Lithium (from Ancient Greek: λίθος, líthos, 'stone') is a chemical element; it has symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element.

Feb 28, 2020 · There are ten known isotopes of lithium, each with different numbers of neutrons and decay paths. Lithium-6 and Lithium-7 are stable isotopes, with Lithium-7 being the most abundant naturally. Some lithium isotopes like Li-3 and Li-11 decay quickly and involve different types of particle emissions.

Mar 26, 2025 · Lithium, chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale. Learn more about the occurrence and uses of lithium.

List, data and properties of all known isotopes of Lithium. 2 natural nuclides and 8 artificial radiosotopes as well as 2 nuclear isomers are known from the alkali metal lithium.

Oct 19, 2017 · Therefore, lithium-8 contains 5 neutrons. Identify the atomic number: Lithium has an atomic number of 3, which means it has 3 protons. Understand mass number: The mass number (A) of lithium-8 is 8. This number represents the total number of protons and neutrons in the nucleus of the atom.

The team also performed experiments with lithium-8 to determine the angle at which neutrinos were ejected during beta decay without neutron emission. When lithium-8 decays, it ejects a beta particle and an antineutrino and is transformed into beryllium-8.
