Sections 2H & 4: Complete the front of the worksheet from class today (Aufbau diagrams) and 1-5 on the back.  Then, in your notebook, write the electron configurations for the following elements:
Xenon, Lead, Mercury and Bromine.

You may want to use this video (Electron Configuration and the Periodic Table), the image on the top of the page and the notes we took in class.

Don't forget:

Also, check out this screen shot of the electron configuration for Polonium. Once we get further along in the p,d & f orbitals, the order of the energy levels gets stranger. Pay attention to atomic numbers and the diagram above! Pay particular attention to what happens after the 6s orbital.

All: We will have the follow-up extra credit session for the Google Expedition to CERN tomorrow during CP in 4K3.
