A Lithium atom has an atomic mass of 6 How many neutrons does this atom have?

This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.


How many protons will lithium have if the mass number is 8?

Lithium with a mass number of 8 will have 3 protons. The mass number represents the total number of protons and neutrons in an atom's nucleus, and since lithium has an atomic number of 3, it means it has 3 protons.


What is lithiums mass number?

The mass number of lithium is 7. This number represents the total number of protons and neutrons in the nucleus of a lithium atom.


Lithium mass number?

Lithium's mass number is 6.941.


How many protons are there in an atom the element lithium if it has an atomic number of 3?

Lithium has 3 protons. The atomic number and the number of protons will be the same.


Explain the difference between atomic number and mass number?

Atomic number is the number of protons in the nucleus of an atom while the mass number is the sum of the protons and neutrons in the nucleus of an atom. for example lithium has an atomic number of 3 and a mass number of 7. Therefore lithium has 3 protons and 4 neutrons.


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.


What does the mass number tell us about lithium?

It tells us the total mass of Protons and Neutrons, in AMU, Atomic Mass Units.


The mass of a proton is 1.00727252 you The mass of a neutron is 1.008665 you What is the difference in the calculated and rest mass of an atom of lithium?

The rest mass of a lithium atom can be calculated by adding up the masses of its protons and neutrons. Lithium has 3 protons and 4 neutrons, so the calculated mass would be (31.00727252 + 41.008665 = 7.01600472 u). The rest mass of a lithium atom is approximately 7.016 u, so the difference between the calculated and rest mass is essentially zero.


What is the number of an atom with 3 protons 4 neutrons and 3 electrons?

The number of protons in the nucleus is given by the atomic number. So in your example, this would be atomic number 3 (lithium). It will have atomic mass of 7 (3 protons + 4 neutrons), and a charge of 0 since there are also 3 electrons to balance the 3 protons.


Which Atom has the greatest mass between Lithium Sulphur oxygen and sodium?

lithium


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.
