Answer 1

The correct statement to describe how to find the number of neutrons to include in the model is:

Subtract the atomic number from the mass number.

This is because the atomic number represents the number of protons in the atom, and the mass number is the sum of protons and neutrons. Therefore, to find the number of neutrons, you can calculate it using the formula:

Number of Neutrons = Mass Number - Atomic Number.
