Where does lithium come from?
Lithium and its compounds were historically isolated and extracted from hard rock but by the 1990s mineral springs, brine pools, and brine deposits had become the dominant source. Most of these were in Chile, Argentina and Bolivia. by 2018 hard rock had once again become a significant contributor, and by 2020 Australia expanded spodumene mining to become the leading lithium producing country in the world. By early 2021, much of the lithium mined globally comes from either "spodumene, the mineral contained in hard rocks found in places such as Australia and North Carolina" or from the salty brine pumped directly out of the ground, as it is in locations in Chile.
How does lithium hydroxide absorb carbon dioxide?
Lithium hydroxide absorbs carbon dioxide from the air by forming lithium carbonate, and is preferred over other alkaline hydroxides for its low weight. Lithium peroxide (Li 2 O 2) in presence of moisture not only reacts with carbon dioxide to form lithium carbonate, but also releases oxygen.
What is the most abundant isotope of lithium?
Naturally occurring lithium is composed of two stable isotopes, 6 Li and 7 Li, the latter being the more abundant (92.5% natural abundance ). Both natural isotopes have anomalously low nuclear binding energy per nucleon (compared to the neighboring elements on the periodic table, helium and beryllium ); lithium is the only low numbered element that can produce net energy through nuclear fission. The two lithium nuclei have lower binding energies per nucleon than any other stable nuclides other than deuterium and helium-3. As a result of this, though very light in atomic weight, lithium is less common in the Solar System than 25 of the first 32 chemical elements. Seven radioisotopes have been characterized, the most stable being 8 Li with a half-life of 838 ms and 9 Li with a half-life of 178 ms. All of the remaining radioactive isotopes have half-lives that are shorter than 8.6 ms. The shortest-lived isotope of lithium is 4 Li, which decays through proton emission and has a half-life of 7.6 × 10 −23 s.

Because lithium is present in cooler, less-massive brown dwarfs, but is destroyed in hotter red dwarf stars, its presence in the stars' spectra can be used in the "lithium test" to differentiate the two, as both are smaller than the Sun. Certain orange stars can also contain a high concentration of lithium.
