Chem1B

This page is first semester only.

To find out what we do in class, check out this page. It is especially useful to determine when points are earned that affect grades. The most recent week is posted on top. (There are two chemistry classes...C1A and C1B....so make sure you are reading for the correct class.)

Week 17, December 17 - 21, 2018

Chem 1B

Monday, 12/17

1. See how well you did your homework...discuss the electron orbital aspect of quantum mechanics model of the atom.

• Discuss what you need to know from section 1 of chapter 5
  • Bold print terms and concepts
  • The ladder analogy of the Bohr model
  • How the Bohr is similar and different from the quantum mechanical model of the atom
  • The different orbital letters and shapes
  • That s has one orbital (2 electrons), p has three orbitals (6 electrons, d has five orbitals (10 electrons)
  • NOT first two columns of Table 5.1 and NOT Table 5.2

2. So, remember all of chapter 4 and section 1 of chapter 5 (notebook entries 61 - 69 and related homework) are on the chemistry test on Finals day. Worth 30 points. Most, and possibly all, will be multiple choice. But beware of multiple choice! (no partial credit!!)

2. Correct NB67

3. Get test back and correct.

4. NB70 PT Color Coded PT by Electron Orbital Sublevel Filling (to begin next semester's study!)

5. Turn in NB today or day of final.

6. (HW) Quiz yourself on topics from notebook 61 - 69 and textbook chapters 4 (all sections, with emphasis of what we studied) and 5 (section 1 only)
