To find the number of neutrons to include in the model of an atom, the correct statement is:
**Subtract the atomic number from the mass number.**
This is because the atomic number (which is the number of protons) is used to calculate the number of neutrons if you know the mass number (which is the total number of protons and neutrons in the nucleus). The formula can be expressed as:
Number of Neutrons = Mass Number - Atomic Number.
