Step 1I'll solve this problem step by step, explaining how to identify an element using its Photoelectron Spectroscopy (PES) spectrum:
Step 2: Understand PES Spectrum Basics
Photoelectron spectroscopy measures the kinetic energy of electrons ejected from an atom when bombarded with high-energy photons. The spectrum provides information about: - Ionization energies - Electron configuration - Number of electron shells
Final Answer
To identify an element from its PES spectrum, carefully analyze the number of peaks, their positions, and relative intensities, then match these characteristics to known elemental electron configurations.
