What is the atomic mass of Li?
The atomic mass of Li, which stands for lithium, is approximately 6.94 atomic mass units (u).
What is the atomic symbol of lithium?
Lithium's atomic symbol is Li. It's atomic number is 3, and it's relative atomic mass (Ar) is 6.9 Lithium is in Group 1 and is highly reactant, most likely to give an electron when forming a compound
What is the number of neutrons for Li?
Subtract number of protons (=atomic number) 3 from the total number of protons AND neutrons ( p+n = mass number) 7, leaves the number of neutrons 47-3=4
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's the difference between atomic number and atomic mass number?
Atomic number is the number of protons in a nuclide. This identifies the element. Mass number is the number of nucleons in a nuclide, a nucleon being a proton or a neutron. This, together with the atomic number, identifies which isotope of the element it is.

Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
What is the atomic mass number of krypton?
83.98 amu is the Atomic Mass, 36 is the atomic number.
What is the total number of neutrons in an atom of 7 lithium 3?
There are 4 neutrons in a lithium-7 atom. Lithium, which has atomic number 3, has 3 protons in its nucleus. If its atomic number is 3 (which is the number of protons in its nucleus) and its mass number is 7, we can find the number of neutrons by subtracting the atomic number from the mass number. In this case, 7 minus 3 equals 4.
