Configuring Electrons
Tomorrow, we'll learn about electron configurations. You should go home and turn to chapter 11 and practice several of these to cement what we learn. I realize that the information is a little overwhelming; however, to understand the material, you must practice what we learned.
The text book has another version of the diagonal rule (Aufbau principle). Also, refer to http://chemtutor.com/struct.htm Scroll down about 2/3 of the way to the "Common Electron Configuration Scheme B" which is also referred to as "follow the yellow brick road." As I explained in class, this is easy to replicate if you know that an energy level has n sublevels.
You might also visit http://www.chem1.com/acad/webtext/atoms/atpt-6.html where you can see the s, p, d, and f blocks on the periodic table.
Another nice place is http://www.shodor.org/unchem/basic/atom/index.html
Pictures of atomic orbitals are found at http://www.humboldt.edu/~rap1/Chem_resrc/AOSup.htm
Work some on your own to reinforce. Test will be on Friday, September 5.
Also, if you did not yet turn in your Atomic Mass of Candium labs, those are due Friday, August 29.
