Atomic number is determined by the number of protons, Atomic Mass is Protons + neutrons (electrons weigh less then 1/1800th of a proton which is so close to nothing that they are usually ignored at most levels) Neutrons and protons each have an atomic weight of 1, if you want to split hairs neutrons are a shade heavier then protons but again at most levels this is insignificant.
We get the number of neutrons. Atomic number is the number of protons, and atomic mass is protons plus neutrons.
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
The atomic number is the same as the number of protons. It is unrelated to the number of neutrons.
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
Atomic mass is the number of protons and neutrons in an atom.
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
The Atomic Mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
Atomic Mass: protons AND neutrons atomic number: just protons
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
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

79; the mass number is the sum of the protons and neutrons, and the atomic number is the number of protons. So if you take the mass number (protons + neutrons) minus the atomic number (protons), you get the number of neutrons.
Protons are positively charged Neutrons are negatively charged The number of protons is the atomic number Protons+Neutrons=Atomic weight
