Detailed explanation-1: -The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. Both of these numbers can be found on the periodic table.
Detailed explanation-2: -If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number. A property closely related to an atom’s mass number is its atomic mass.
Detailed explanation-3: -The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Detailed explanation-4: -How do you find the number of neutrons in an element on the periodic table? Hint: To find the number of neutrons, you should first know about the number of protons present in an atom and then, subtract the number of proton from the atomic mass of that very element, you will get the number of neutrons of the atom.
