Chemblog!

Halloween: good, clean, wholesome fun! Enjoy the fun/parties tonight and then go to your local dentist.

AP: had our second Thermo exam; we finish Thermodynamics, complete with Entropy and Gibbs Free Energy, in April (a few weeks before the big AP Exam!).
For now, it's back to Quantum...I'll have assigned reading in the text, Chapter 7.1 and 7.2, and some questions to do tomorrow; I'll post some "never forget" questions also.

D/G: We (finally) got to the modern quantum mechanical model of the atom, specifically focusing on PrinciPAL energy levels, sublevels ( which are NOT separate FROM but part OF a princiPAL energy level), and orbitals (OF a given sublevel). These energy SUBLEVELS are THE solutions to the Schrodinger equation, which gives the possible energies of electron(s) in an atom.
We have a written exam on Thursday; BE PREPARED. If you have questions tomorrow, you can always email me, that's what our class email is for.

E: We focused on Bohr Models of the atom that could be drawn from modern quantum model electron configurations. We then introduced the Periodic Table, which is our NEW unit.
