Electron Configurations (Energy Level Order Method)

Example problems from the Electron Configurations HW assignment (electron configurations and determining how many unpaired electrons). This video uses the energy level order method for writing electron configurations. If you're using the periodic table method for electron configurations, use the following video: https://youtu.be/aL-6cA2615c Click the time to jump to that problem: Lithium 1:29 Argon 4:53 Iron 8:02
