By the process of elimination. For example, The atomic weight of an atom is just the number of its protons, and the Atomic Mass is the total weight of protons and neutrons in the atom.
So, the atomic weight of Oxygen is 8(protons) and the atomic mass is 16(protons + neutrons) so we can tell that there are 8 protons and 8 neutrons.

Where do you find neutrons?
You find the neutrons with the protons, inside the nucleus.Most neutrons are in the nucleus of atoms.
Most atoms are composed of electrons protons and neutrons. Which particles are found in the nucleus of a gold atom?
Not just "most" atoms , but all atoms are composed of protons and neutrons, which are found in the nucleus, and electrons surrounding the nucleus in the electron cloud. And these atoms include gold.
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
Where in an atom do you find a neutrons?
you can find the neutron in the center of an atom.
How do you find the number of neutrons in an elements atoms?
number of neutrons = mass number - atomic number
How do you find the neutrons that are in the nucleus?
Number of neutrons = Atomic mass of an isotope - Number of protons (Atomic number)
How do yo find an atoms mass number?
The mass number of an atom is determined by adding together the number of protons and neutrons in the nucleus of the atom. This information can be found on the periodic table of elements where the mass number is typically listed underneath the symbol of the element.
How can subatomic particles help identify an element?
you find the real atomic twist in the vein
How do you find the number of neutrons in the nucleus of uranium?
Number of neutrons in an atomic nucleus = Atomic mass of an isotope - Number of protons in the nucleus For uranium the number of protons is 92; each isotope has of course a different mass.
How can you find the mass from the number of atoms?
protons plus the number of neutrons.
How do you find neutrons in an element?
In order to find the number of neutrons in the atoms of an element, you must specify the isotope that you are interested in. Isotopes are specified according to their mass number. For example carbon-12 is the isotope of carbon that has a mass number of 12, and carbon-14 is the isotope of carbon that has a mass number of 14. All atoms of the same element, regardless of mass number, have the same number of protons, which is the element's atomic number. To determine the number of neutrons in an isotope, you subtract the atomic number from the mass number. For example, the atomic number of carbon is 6, which means that all carbon atoms contain 6 protons in their nuclei. So, to find the number of neutrons in a carbon-12 atom, subtract 6 from 12, and you get 6 neutrons in the atoms of carbon-12. To find the number of neutrons in a carbon-14 atom, subtract 6 from 14, and you get 8 neutrons in the atoms of carbon-14.
How do you find the mass number if you have the atomic number of an isotope?
Mass number is the sum of protons and neutrons in the nucleus of the atoms of a particular isotope. The atomic number is the number of protons, so you would also need to know the number of neutrons. You could not determine the mass number from the atomic number alone.
