Lithium-4 contains three protons and one neutron. It is the shortest-lived known isotope of lithium, with a half-life of 91(9) yoctoseconds (9.1(9)×10 s) and decays by proton emission to helium-3. Lithium-4 can be formed as an intermediate in some nuclear fusion reactions. Meer weergeven 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 Meer weergeven Lithium-3, also known as the triproton, would consist of three protons and zero neutrons. It was reported as proton unbound in 1969, but this result was not accepted and its existence is thus unproven. No other resonances attributable to Li have … Meer weergeven Lithium-7 is by far the most abundant isotope of lithium, making up between 92.2% and 98.1% of all terrestrial lithium.
