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… WebBeryllium fluoride is the inorganic compound with the formula Be F 2. This white solid is the principal precursor for the manufacture of beryllium metal.

WebAboutTranscript. An element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay. Sort by: fish in hawaii with longest name
