The correct statement for finding the number of neutrons to include in the model is:

Subtract the atomic number from the mass number.

The number of neutrons in an atom can be calculated using the formula:

Number of Neutrons = Mass Number - Atomic Number

where the mass number is the sum of protons and neutrons, and the atomic number is the number of protons.
