Answer 1

The correct statement to find the number of neutrons to include in the 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 is the total number of protons and neutrons in the atom. Therefore, to find the number of neutrons, you can use the formula:

\[ \text{Number of Neutrons} = \text{Mass Number} - \text{Atomic Number} \]
