WebNaturally occurring lithium is composed of two stable isotopes, 6Li and 7Li, the latter being the more abundant (92.5% natural abundance). Lithium-6 is valuable as the source material for the production of tritium (hydrogen-3) and as an absorber of neutrons in nuclear fusion reactions. Natural lithium contains about 7.5 percent lithium-6. WebFrom the isotopic decomposition of normal lithium one finds that the mass-7 isotope, 7Li, is the more abundant of lithium s two isotopes 92.5% of terrestrial Li. The cosmic issues …
