A student wants to draw a model of an atom. Which statement describes how to find the number of neutrons to include in this model?

Answer 1

To find the number of neutrons to include in the model of an atom, the student should subtract the atomic number (number of protons) from the atomic mass number. The atomic mass number represents the total number of protons and neutrons in the atom. The difference between the atomic mass number and the atomic number will give the number of neutrons in the atom.
