Lithium is a metal element. Atomic Mass of it is 7.
The atomic number of lithium is 3. The only stable isotope of lithium has 4 neutrons. Therefore its relative atomic mass is 7.
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6.The atomic mass of Lithium-Li is 6.941 grams.
lithium is a metal element. Atomic mass of it is 6.941.
Lithium is a meta element. Atomic mass of it is 7.
The atomic mass of lithium is approximately 6.94 atomic mass units.
The atomic mass of lithium-6 is 6.941 amu
The atomic mass of Lithium(Li) is 6.941g.
The atomic mass of lithium is found by adding the mass of its protons and neutrons in its nucleus. It is calculated by taking the weighted average of the isotopes of lithium found in nature, where lithium-6 and lithium-7 are the most abundant isotopes. The atomic mass of lithium is approximately 6.94 atomic mass units.
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
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.
Carbon (12) has a higher atomic mass than lithium (7).
The molar mass of lithium selenide (Li2Se) can be calculated by adding the atomic masses of lithium and selenium together. The atomic mass of lithium is approximately 6.94 g/mol, and the atomic mass of selenium is approximately 78.97 g/mol. Therefore, the molar mass of lithium selenide is approximately 163.85 g/mol.
