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
Bromine has the atomic number 35, which means there are 35 protons in the nucleus of an atom of bromine.The mass number (also known as the atomic mass number) of an element is the sum of the protons and neutrons in the nucleus.Bromine's mass number is 80, so there must be 35 protons and 45 neutrons in an atom of bromine.Sorry we do not know what you mean by "newtrons" or "deos".
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
The atomic number of the potassium is 19. So the number of protons and electrons is 19 in the atom of potassium. The number of neutrons can be calculated as mass number minus atomic number. It comes to be 39 minus 19. That is 20.
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
You subtract the atomic number from the mass number.
The answer is that it is neutrons that account for the difference between atomic weight and atomic number. The atomic number is the number of protons or the number of electrons in the atom, since they are normally equal. The atomic weightis the sum of the total number of protons, electrons AND neutrons in the atom. Knowing both the atomic number and the atomic weight of an atom lets you know the number of neutrons in the atom (the isotope). Example: Uranium, Atomic Number 92, Atomic Weight 235. The atomic number tell you that the uranium atom has 92 protons and 92 electrons. The atomic weight tells you that it has a combined total of 235 protons, electrons and neutrons. Since you know from the atomic number that there is a total of 184 protons and electrons in the atom (92 + 92) and from the atomic weight that the total number of protons, electons and neutrons is 235 (92 + 92 + X = 235), you now know that there are 151 neutrons in that uranium atom. The atomic number and atomic weight together tell you that the uranium atom 235 has 92 protons, 92 electons and 151 neutrons.

It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
Neutrons, like protons are considered to have a mass of about 1. To find the number of neutrons, subtract the atomic number from the atomic mass.

You look up antimony. You discover its symbol is SB. You look on your periodic table. You come to the symbol SB. You see that it is number 51. You know that is also the number of protons in the atom. You know that 122 is the atomic weight. You know that the Atomic Weight mainly comes from the weight of the neutrons and protons. You know that when you have the atomic weight you can subtract the atomic number from the atomic weight and get the number of neutrons.

number of protons and electrons present in an element is equal to the atomic number of that element while number of neutrons is equal to mass number - atomic number/number of protons/number of electrons.
