Lithium isotope carbonate

Lithium-7 is by far the most abundant isotope of lithium, making up between 92.2% and 98.1% of all terrestrial lithium. A lithium-7 atom contains three protons, four neutrons, and three electrons. Because of its nuclear properties, lithium-7 is less common than helium, carbon, nitrogen, or oxygen in the Universe, even though the latter three all have heavier nuclei. The industrial production of lithium-6 results in a waste product which is enriched in lithium-7 an… Web11 apr. 2024 · The contribution of carbonates is another possible explanation for Mg isotopic variation, as carbonate minerals are an isotopically light reservoir of Mg, ...
