A mass spectrometer is used to analyze an unknown elemental vapor composed of diatomic molecules, \(\text{X}_2\). All detected ions have a charge of \(+1\). The peaks near \(m/z=80\) result from \(\text{X}^+\) fragments, whereas the peaks near \(m/z=160\) result from intact \(\text{X}_2^+\) molecular ions.

Which particulate representation is consistent with the relative abundances of the three molecular ions shown in the spectrum?
