Lithium abundance
Web6 jul. 2024 · For example, the abundance of one form of lithium, or isotope — lithium-7 — mostly results from the production and decay of beryllium-7. But it has either been overestimated in theory, underobserved in reality, or a combination of the two. This needs to be resolved in order to really understand what took place way back then.” Web14 aug. 2024 · Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1.
