Lithium has three protons because elements always have the same number of protons.


If the atomic mass of lithium is 6.941 and it exists as lithium-6 and lithium-7 what percent of the isotope is lithium-7?

To determine the percentage of lithium-7, we need to calculate the relative abundance of each isotope considering their atomic masses. Given that the atomic mass of lithium-6 is 6.015 and that of lithium-7 is 7.016, the percentage of lithium-7 is approximately 92.5% based on natural abundance.


What is the mass number for lithium?

Lithium is element #3. That, of course, is the atomic number - the number of protons. The atomic mass will of course depend on the specific isotope. The most common isotope is Lithium-7, that is, atomic mass = 7. Lithium-6 also occurs in nature as a stable isotope.


Number of isotopes in lithium?

Lithium has two stable isotopes, lithium-6 and lithium-7. There are also several radioactive isotopes of lithium, with lithium-8 being the most common radioactive isotope.


Why is the mass number of lithium 7?

6.941 is the average mass of lithium's isotopes. The majority of lithium (on average about 92.5%) is lithium-7 with 3 protons and 4 neutrons while about 7.5% is lithium-6 with 3 protons and 3 neutrons. A number of other isotopes exist but only in trace amounts.
