Is lithium an ion or isotope
Naturally occurring lithium (3Li) is composed of two stable isotopes, lithium-6 and lithium-7, with the latter being far more abundant on Earth. Both of the natural isotopes have an unexpectedly low nuclear binding energy per nucleon (5332.3312(3) MeV for lithium-6 and 5606.4401(6) MeV for lithium-7) when compared with the adjacent lighter and heavier elements, helium (7073.9156(4) MeV for helium-4) and beryllium (6462.6693(85) MeV for beryllium-9). The longest-lived radioisot… WitrynaA depletion of ~Li in the effluent lithium acetate occurred in the first four c3~ F. H. SPEDDING, J. E. POWEI-L and H. J. SVEC, J. Amer. Chem.
