To find the number of neutrons to include in the model of an atom, you should:
**Subtract the atomic number from the mass number.**
This is because the atomic number represents the number of protons (which is the same as the number of electrons in a neutral atom), and the mass number represents the total number of protons and neutrons. Thus, the number of neutrons can be calculated using the formula:
**Number of Neutrons = Mass Number - Atomic Number**.
**Subtract the atomic number from the mass number.**
This is because the atomic number represents the number of protons (which is the same as the number of electrons in a neutral atom), and the mass number represents the total number of protons and neutrons. Thus, the number of neutrons can be calculated using the formula:
