AP Chemistry
1.7 Periodic Trends
1.6 Photoelectron Spectroscopy
1.5 Atomic Structure and Electron Configuration
Photoelectron spectroscopy (PES) is used to measure the binding energies of electrons in atoms. The complete PES spectrum of gaseous neon (
\(\text{Ne}\), \(Z = 10\)) exhibits a peak corresponding to the \(1s\) subshell at approximately \(84\text{ MJ/mol}\). Which of the following statements best predicts and explains the binding energy of the \(1s\) electrons in gaseous argon (
\(\text{Ar}\), \(Z = 18\)) compared to that in \(\text{Ne}\)?
