WebLithium (Li) Standard atomic mass: [6.941(2)] u. Naturally occurring lithium is composed of two stable isotopes 6 Li and 7 Li, the latter being the more abundant (92.5% natural abundance).Seven radioisotopes have been characterized, the most stable being 8 Li with a half-life of 838 ms and 9 Li with a half-life of 178.3 ms. All of the remaining radioactive … WebWe know that the atomic number of lithium is 3 and the atomic mass number is about 7. Neutron = 7 – 3 = 4. Therefore, a lithium atom has four neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone.
