The correct statement to describe how to find the number of neutrons to include in a model of an atom is:
**Subtract the atomic number from the mass number.**
This is because the atomic number represents the number of protons, and the mass number represents the total number of protons and neutrons in the nucleus. Therefore, the formula to find the number of neutrons (N) is:
\[ N = \text{Mass Number} - \text{Atomic Number} \]
