Day 4 Pre-Class Podia Problem: Electron Configuration and Magnetism

This Podia problem is based on today’s pre-class material; working through that material will help you solve the problem.

Experimental measurements of the attraction of solid iron(III) chloride to a magnetic field can be interpreted to show that Fe3+ ions have five unpaired electrons. A fellow student claims that this shows that the 4s electrons must have been removed when iron atoms ionize. Write a few sentences that confirm or dispute the student’s argument.

Two days before the next whole-class session, this Podia question will become live on Podia, where you can submit your answer.
