To find the number of neutrons to include in a model of an atom, you should subtract the atomic number from the mass number.

The atomic number represents the number of protons in the nucleus, and the mass number is the total number of protons and neutrons in the nucleus. Therefore, if you subtract the atomic number (number of protons) from the mass number, you will get the number of neutrons.

So, the correct answer is: Subtract the atomic number from the mass number.
