Photoelectron spectra of two isoelectronic species showing relative electron counts versus binding energy.
Photoelectron spectra of two isoelectronic species showing relative electron counts versus binding energy.
The complete photoelectron spectra of two isoelectronic chemical species, gas-phase \(\text{Ne}\) and gas-phase \(\text{Na}^+\), are shown in the figure. Which of the following correctly identifies the spectrum that corresponds to \(\text{Na}^+\) and provides the best explanation for the difference in peak positions between the two spectra?
