The photoelectron spectrum (PES) of gaseous neutral iron, \(\text{Fe}\), exhibits seven distinct peaks corresponding to the occupied subshells \(1s, 2s, 2p, 3s, 3p, 3d,\) and \(4s\). Which of the following best predicts the changes observed in the PES spectrum when neutral \(\text{Fe}\) is ionized to form gaseous \(\text{Fe}^{2+}\), and provides the correct physical justification?
