Answer 1

The correct statement that describes how to find the number of neutrons to include in the model of an atom is:

Subtract the atomic number from the mass number.

The atomic number represents the number of protons in the atom, and the mass number represents the total number of protons and neutrons. Therefore, to find the number of neutrons, you subtract the atomic number (number of protons) from the mass number.
