AP Chemistry
1.7 Periodic Trends
1.6 Photoelectron Spectroscopy
A student analyzes the photoelectron spectroscopy (PES) data for neutral boron (\(\text{B}\)) atoms shown in the table below and attempts to predict the PES spectrum for neutral carbon (\(\text{C}\)) atoms.
Which of the following statements correctly predicts and justifies the relative binding energy of the \(2p\) electrons in \(\text{C}\) compared to the \(2p\) electrons in \(\text{B}\)?
| Subshell | Binding energy (\(\text{MJ/mol}\)) |
|---|---|
| \(1s\) | \(19.3\) |
| \(2s\) | \(1.36\) |
| \(2p\) | \(0.80\) |
