We took the atoms test today. You will be able to see how you did over the next few days if you check your gradebook online account at student.cps.k12.il.us
Otherwise, the grades will be posted, along with your most recent binder and HW grades, on the wall when you return.
Those of you failing due to a lack of completed work on time, please be smart and use the time over the break to do any one of three things to improve your grade:
1) Complete old HW that you never did on time (this includes any HW that you wrote down in class on Monday while we were checking it, because this is NOT doing it on time)
2) If you missed any days of class, get the missing do nows, notes and worksheets from a classmate and copy them into your binder.
3) Complete the extra credit HW packet. If you did not pick it up from me on Thursday after school, you can get it here (click for link).
Have a good break, and get your mind right for school when we pick back up again on Oct. 17th.

No new HW assignment for Tuesday, Sept. 27
The classes that met today were given time to begin work on a 'Make-up HW' assignment, where you turn in all HW that you have not done on time throughout the year. Do NOT turn this assignment in one piece at a time; all of this work is to be stapled together and turned in during the first few days we are back in school (starting Oct. 17).
Please use common sense and realize that you must complete all of the assignments for a given week, in order to get the check minus makeup credit for that week.

HW#7a -- Monday, Sept. 26
Write down the electron configuration for these elements:
(Remember to include every orbital that you cross, on the way to get to the element!)
1) Zinc
2) Sulfur
3) Bromine
4) Cadmium
For example, let's do nitrogen. You'll need the HALF SHEET elements table for this, as it shows you where the different orbitals (s, p, d and f) are.
Start in teh top left box (hydrogen, or "H") and count every electron that you pass as you move in a line to the right. I first pass two electrons in the 1s section, then two electrons in the 2s section, and finally three in 2p. Since we've now arrived at and counted the electron for the symbol "N," we're done. You would write the result like this:
