Below are sample questions representative of the exercises included on this worksheet and related 11.131 Photoelectron Spectroscopy in Atomic Structure skill assessments:

Problem 1Difficulty: Mastery

A capstone PES spectrum has peak areas 2, 2, 6, 2, and 4 assigned from highest to lowest binding-energy shells/subshells as 1s, 2s, 2p, 3s, and 3p. Which conclusion is strongest?

AThe data identify neon because the three highest binding-energy peaks total ten electrons and all lower peaks should be ignored.

BThe data prove the sample's isotope mass but not its electron configuration.

CThe data show all electrons are in one shell because there are five peaks.

DThe data identify sulfur and support shell/subshell structure because peak areas give electron counts and peak positions separate subshell energies.

Solution & Explanation:The peak areas add to 16 electrons: 1s² 2s² 2p⁶ 3s² 3p⁴. This identifies sulfur and uses both area and position as evidence for electron configuration and subshell structure.

Problem 2Difficulty: Mastery

A PES comparison shows the 2p peaks of B, C, and N shifting to higher binding energy, but the 2s peaks also shift higher. What is the best general explanation?

AThe principal shell number changes from 2 to 3 across B, C, and N.

BPeak shifts are caused only by changes in neutron count.

CIncreasing nuclear charge across the period raises effective nuclear charge for electrons in the same principal shell, though subshells remain distinct.

DAll 2s and 2p electrons become equally bound at higher atomic number.

Solution & Explanation:Across a period, added protons increase attraction for both 2s and 2p electrons. PES still shows 2s and 2p as distinct peaks because penetration and shielding differ.

Problem 3Difficulty: Mastery

An unknown atom's PES table includes a neon-core pattern plus valence peaks 3s area 2 and 3p area 5. Which conclusion is best supported?

AThe atom is sulfur with electron configuration [Ne]3s² 3p⁴.

BThe atom is chlorine with electron configuration [Ne]3s² 3p⁵.

CThe atom is argon with electron configuration [Ne]3s² 3p⁶.

DThe atom is aluminum with electron configuration [Ne]3s² 3p¹.

Solution & Explanation:A neon core has 10 electrons. Adding 3s² and 3p⁵ gives 17 total electrons, identifying chlorine.
