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.

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.
What does the mass number tell us about lithium?
It tells us the total mass of Protons and Neutrons, in AMU, Atomic Mass Units.
How many electrons does lithium 7 have?
A neutral lithium atom has 3 electrons, the same as the number of protons, which is the atomic number of lithium. There is no lithium ion with a charge of 7+. If you mean lithium with a mass number of 7, the number of protons is 3 and the number of neutrons is 4.
What is the total number of neutrons in an atom of 7 lithium 3?
The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively. The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively.
How many protons will lithium have if the mass number is 8?
lithium has 3 protons which would also be 3 electrons.
Lithium mass number?
Lithium's mass number is 6.941.
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 has a mass number of seven?
Lithium is an element with an atomic number of 3 and an atomic mass of 7.
What is the mass number for lithuim?
Lithium is a metal element. Atomic mass of it 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.

lithium has 3 protons which would also be 3 electrons.
Determine the number of electrons in a neutral atom of lithium?
By consulting a periodic table, you can find the atomic number of lithium (which equals its proton number), as well as its average number of neutrons (represented by the mass number - simply take the proton number away from the mass number).
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.
