Atomic weight minus number of protons.
The atomic weight minus the number of protons = the atom's neutrons.
The number of protons and neutrons in the nucleus
Protons and neutrons= mass
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
A typical atom of iodine contains 74 neutrons.
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.
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
45 neutrons
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.
A stable atom of Zinc (Zn) typically has 34 neutrons.
To find the number of neutrons in an atom, you subtract the atomic number (which represents the number of protons) from the atomic mass. If the atomic mass is 36 and the atomic number is, for example, 18 (like Argon), you would calculate it as 36 - 18 = 18 neutrons. Thus, the atom would have 18 neutrons in its nucleus.
52 neutrons.
