The number of protons + the number of neutrons in an atom is called the mass
number or the nucleon number. Thus, chlorine-35 has a mass number (nucleon
number) of 35 (17 -I- 18) and chlorine-37 has a mass number (nucleon number)
of ...

Interpretation of
Mass Spectra
An odd number of nitrogen atoms causes M+ to be at an odd mass number: NH3,
m/z 17; C2H5NH2, m/z 45; and quinoline, C9H7N, m/z 129. Thus if the ion of
highest m/z is at an odd mass number, to be the molecular ion it must contain an
