Photoelectron spectroscopy can be used to determine the energies of atomic orbitals by measuring the energies required

Question:

Photoelectron spectroscopy can be used to determine the energies of atomic orbitals by measuring the energies required to remove electrons from them. The following peaks were observed in the photoelectron spectra for two elements.

Identify the elements, write their electron configurations, and explain your reasoning:

(a) 75.7 eV (7.30 MJ · mol-1) and 5.38 eV (0.519 MJ · mol-1)

(b) 153 eV (14.8 MJ · mol-1) and 9.33 eV (0.90 MJ · mol-1)
