"Lithium has two isotopes. Lithium-6 has an actual mass of 6.015 g/mol and lithium-7 has a mass of 7.016 g/mol. In any sample of lithium atoms, 7.59% will be lithium-6 and 92.41% will be lithium-7. Calculate the average molar mass of lithium.
Isotope Notation - Chemistry - Socratic
Isotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope's mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words. Additionally, #"N"="A"-"Z"#. Example 1: What is the isotopic notation for ...

What is the average atomic mass of lithium? - Socratic
2016年1月30日 · The major isotopes of lithium are (i) ""^7Li, and (ii) ""^6Li. The weighted average of these isotopes is 6.941 g*mol^-1. You will have to look up the isotopic distribution of lithium nuclei. ALL lithium nuclei have 3 positively charged nuclear particles, protons, i.e. Z = 3. These 3 particles give rise to the element's identity. If you take the weighted average of ALL lithium …
