Answer 1

The correct statement for finding 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 also the number of electrons in a neutral atom), while the mass number is the total number of protons and neutrons in the nucleus. Thus, the number of neutrons can be found using the formula:

Number of neutrons = Mass number - Atomic number.
