In the depleted lithium, the relative abundance of lithium-6 can be reduced to as little as 20 percent of its nominal value, giving an atomic mass for the discharged [clarification needed] lithium that can range from about 6.94 Da to about 7.00 Da. answers 1. One of them has an abundance of $92.5 \%,$ and the other has an abundance of $7.5 \% .$ Knowing that the atomic mass of lithium is $6.941,$ which is the more abundant isotope? The relative abundance of Li-6 is 7.42% and the relative abundance of Li-7 is 92.58%. The mass of the neutral lithium- 7 atom is 7.016004 amu. Under standard conditions, it is the lightest metal and the lightest solid element. . As hydroxide it is necessary in small quantities for safe operation in pressurised water reactor (PWR) cooling systems as a pH stabilizer, to reduce corrosion in the primary circuit. Solution for Lithium has two isotopes, 6Li (mass = 6.015 u) and 7Li (mass = 7.016 u). The role of Thallium-201 scintigraphy and Tc-99m pentavalent dimercaptosuccinic acid in diagnosis and grading of chondrosarcoma. It has the atomic symbol Li, atomic number 3, and atomic weight [6.938; 6.997]. But in fact, lithium-7 creates gobs of tritium, much more than lithium-6. Mass of 1 proton = 1.0073 atomic mass units. 2. Lithium (atomic symbol: Li, atomic number: 3) is a Block S, Group 1, Period 2 element with an atomic weight of 6.94. 6.01512 amu 7.01600 amu C. 6.41548 atoms. Lithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure.
