Hydrogen has 1 as its atomic number. That's because it has one proton in its nucleus. Hydrogen has three isotopes. Each isotope has one proton in its nucleus (naturally, because that's what makes it hydrogen). Atomic Mass is the number of protons plus the number of neutrons in an atom's nucleus. Let's look at each isotope of hydrogen. "Simple" hydrogen has only the 1 proton in its nucleus. It's atomic number is 1 and its mass number is 1 (the 1 proton plus zero neutrons). Heavy hydrogen has 1 proton and 1 neutron in its nucleus. It's atomic number is 1 and its mass number is 2 (the 1 proton plus 1 neutron). Heavy, heavy hydrogen has 1 proton and 2 neutrons in its nucleus. It's atomic number is 1 and its mass number is 3 (the 1 proton plus 2 neutrons).

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 the atomic mass for lithium 3?
Lithium is a meta element. Atomic mass of it is 7.
How many nuetrons and electrons does lithium have?
There are 3 neutrons in lithium. Take atomic mass - atomic number. ex: Beryllium, atomic mass: 9, atomic number:4 so 9 - 4 equal 5.
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).
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 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?

What has a mass number of seven?
Lithium is an element with an atomic number of 3 and an atomic mass of 7.
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 atomic mass of lithium?
lithium is a metal element. Atomic mass of it is 6.941.
What is the mass number for lithuim?
Lithium is a metal element. Atomic mass of it is 7.
What is the atomic mass for lithium 3?
Lithium is a meta element. Atomic mass of it is 7.
How many atomic mass does lithium have?
Lithium is a metal element. Atomic mass of it is 7.
What is Atomic mass of lithium-6?
The atomic mass of lithium-6 is 6.941 amu
How many nuetrons and electrons does lithium have?
There are 3 neutrons in lithium. Take atomic mass - atomic number. ex: Beryllium, atomic mass: 9, atomic number:4 so 9 - 4 equal 5.
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.
