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.
How many protons are in a lithium nucleus?
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science
What is the mass defect of lithium-7 Assume the following Atomic number of lithium 3 Atomic mass of lithium 7.016003 atomic mass units. Mass of 1 proton 1.007276 atomic mass units. Mass of 1 neutron 1?
To calculate the mass defect of lithium-7, we use the formula: Mass defect = (mass of protons + mass of neutrons) - mass of lithium-7. Given that lithium-7 has 3 protons and 4 neutrons, the total mass of protons is 3 x 1.007276 = 3.021828 amu, and the total mass of neutrons is 4 x 1 = 4 amu. Therefore, the total mass of protons and neutrons is 3.021828 + 4 = 7.021828 amu. The mass defect is then 7.021828 - 7.016003 = 0.005825 amu.
if a lithium nucleus contains 3 protons and 4 neutrons. What is its atomic mass?
Lithium by default contains 3 protons and 4 neutrons so its atomic mass is 6.941 amu (atomic mass units)
The atomic weight of lithium is 6.941 amu What best describes what this value measures?
The atomic weight of lithium (6.941 amu) measures the average mass of an atom of lithium compared to 1/12 of the mass of a carbon-12 atom. It represents the sum of protons and neutrons in the nucleus of a lithium atom.
What is the atomic mass of lithium?
The atomic number of lithium is 3. The only stable isotope of lithium has 4 neutrons. Therefore its relative atomic mass is 7.
What is lithium atomic mass?
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.

What is Atomic mass of lithium-6?
The atomic mass of lithium-6 is 6.941 amu
What is the atomic mas of lithium?
The atomic mass of Lithium(Li) is 6.941g.
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.
Which one has a greater atomic mass lithium or carbon?
Carbon (12) has a higher atomic mass than lithium (7).
What is lithuim atomic mass?
Lithium is a metal element. Atomic mass of it is 6.941.
What is the atomic mass of lithuim?
The average Atomic Mass of Lithium (Li) is 6.941.
What is the molar mass of lithium selenide?
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.
