This bundle includes resources you can use to help your students master Topic 6 (Photoelectron Spectroscopy) in Unit 1: Atomic Structure and Properties.

It includes:

• Google Slides lesson
• Practice Problems (for homework or in-class)
• Cards Activity for in-class practice and review

The Google Slides Slides Lesson includes 34 slides that can be covered in 1-2 class periods. The Practice Problems Worksheet is a 2-page printable PDF worksheet that can be used as a homework assignment or in-class practice, if you have a long block. The PES Cards Activity is a printable PDF resource that you can print, laminate, and use with your students in multiple ways to identify elements by their PES, write electron configuration based on PES, or sketch a PES for an element. Great for the initial lesson, and review prior to the unit test and AP Exam..

These resources are aligned to the learning objective and essential knowledge for this topic in the current (2025) AP Chemistry Course Exam and Description:

• Learning Objective 1.6.A Explain the relationship between the photoelectron spectrum of an atom or ion and:
  • 1. The electron configuration of the species.
  • 2. The interactions between the electrons and the nucleus.
• Essential Knowledge 1.6.A.1: The energies of the electrons in a given shell can be measured experimentally with photoelectron spectroscopy (PES). The position of each peak in the PES spectrum is related to the energy required to remove an electron from the corresponding subshell, and the height of each peak is (ideally) proportional to the number of electrons in that subshell.
