Photoelectron Spectroscopy - AP Chem Unit 1, Topic 6

In this video, Mr. Krug shows students the easy way to interpret a photoelectron spectroscopy (PES) diagram, working several examples. He shows how each peak of a PES diagram correlates to a specific sublevel in an atom, and how the data on the diagram can be used to calculate the ionization energy of an element.

Your videos are really helpful as review before my ap chem class starts!

Thanks for watching! Best wishes on your AP class this year!

I’m doing this in my AP chem class and wanted some review. This is great!

[@JeremyKrug]

Excellent. You will do great in your AP class!

What a fantastic and simple explanation. Thank you!

Thank you so much Mr Krug im watching all your videos! ap chem is days away! I have a question, why is the ionization of the 1s2 sublevel higher than the others?

They're closer to the nucleus than any other electrons
