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 … WebSince lithium lithium 's atomic number is 3 3, Li Li has 3 3 protons. 3 3 protons. Fill in the known values where N N represents the number of neutrons. 7 = 3+ N 7 = 3 + N. Rewrite the equation as 3+N = 7 3 + N = 7. 3+N = 7 3 + N = 7. Move all terms not containing N N to the right side of the equation.

Web13 jan. 2024 · The isotope of Lithium-7 has a mass number of 7. And the isotope of Lithium-8 has 5 neutrons. Given data: The number of protons in a lithium-7 isotope is, … WebLithium-6 has 3 protons (as it must if it is to be the element Lithium) but only 3 neutrons, so it has a mass number of 6. The atoms of these two isotopes behave almost exactly the same way when doing chemistry, since the atomic electrons only care about the charge of the nucleus, but the physical properties of these two nuclei are very different. graduation pictures tumblr white gowns
