you don't calculate it, you look at the number that is usally above the chemical symbol on the periodic table.
the Atomic Mass number is the number of protons/electrons in an atom
The characteristic of an atom that is not used to determine the number of neutrons is its atomic number. The atomic number indicates the number of protons in an atom, while the number of neutrons is derived from the difference between the atomic mass (which is the total number of protons and neutrons) and the atomic number. Therefore, only the atomic mass and the atomic number are needed to calculate the number of neutrons.
To calculate the number of protons in an atom, use the atomic number (Z), which represents the number of protons. The number of neutrons can be calculated by subtracting the atomic number from the mass number (A = Z + N). Electrons are the same as the number of protons in a neutral atom.
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.
The atomic weight minus the number of protons = the atom's neutrons.
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps

Look up the atomic number of the element. The atomic number is the number of protons, in a neutral atom this is the same as the number of electrons.

To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
equal to number of protons
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
