APFIVE Photoelectron Spectrum Peak Analysis
The photoelectron spectrum of an element has four peaks. The peak at the highest binding energy has a relative height of 2, while the other three peaks have relative heights of 8, 8, and 2. Which of the following statements best explains these observations?
A
The 2p orbital contains 2 electrons with the highest binding energy
B
The 3d orbital contains 2 electrons with the lowest binding energy
C
The valence electrons have the highest binding energy
D
The 1s orbital contains 2 electrons corresponding to the highest binding energy peak
