In order to determine the number of neutrons within an atom, one should take the atomic mass number and subtract the atomic number. The atomic number signifies the number of protons present, while the atomic mass comprises both protons and neutrons. As such, the discrepancy between these two values will reveal the quantity of neutrons.
