Lithium (from Greek: λίθος, romanized: lithos, lit. 'stone') is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as purified kerosen… WebSECTION 7. HANDLING AND STORAGE.

WebNuclei of lithium can have 3, 4 or 5 neutrons. We call these different isotopes of lithium. Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers. The isotopes of lithium have mass numbers 6, 7 and 8. 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 … 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 Colex separation Lithium-6 has a greater affinity than lithium-7 for the element mercury. When an amalgam of lithium and mercury is added to solutions containing lithium hydroxide, the lithium-6 becomes more concentrated in the … Meer weergeven 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 Meer weergeven Lithium-8 has been proposed as a source of 6.4 MeV electron antineutrinos generated by the inverse beta decay to Beryllium-8. … Meer weergeven 1. ^ Li – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits. 3. ^ # – Atomic mass marked #: value and uncertainty derived not from purely experimental data, but at least partly from … 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.
