To celebrate the 150th anniversary of the periodic table, Bloomberg Businessweek has devoted their entire 2 Sep 2019 issue to the topic. The issue includes a clickable periodic table with entertaining and/or informative commentaries on specific elements.

Chemical and Engineering News, the weekly trade magazine of the American Chemical Society, also presented a clickable periodic table in the 19 Oct 2009 issue, with each element associated with an essay by an expert in that element.

The midterm exam will be held during class hours this Thu, 24 Oct, from 10-11:20am (80 min total exam time). Students with last names starting with A through M will sit the exam in MC 4040 (the usual class lecture room)); students with last names N through Z will sit the exam in EV3 4412.

The midterm will cover all materials through the last lecture (Thu, 10 Oct) before break week, through the topics of the angular overlap method and Jahn-Teller distortions (lecture notes 5), and Chapters 9 and 10 of the textbook. Bring a pencil or pen; a periodic table, relevant character and AOM tables, and important formulae will be provided, and simple calculators and molecular model kits are permitted.

To assist students with preparation for the upcoming exam, course TA Max Hamilton will hold office hours on Tue, 22 Oct, 3:30-5pm, in C2 381, and Prof. Lee will hold office hours on Wed, 23 Oct, 2-4pm, in C2 382. Both of us are also available by appointment. Because of the exam on Thu, Max's normal office hour is cancelled for this week.

23-Oct-19

It has come to our attention that there are errors in the AOM discussion and energy diagrams in MF&T, specifically in the treatment of the ligand-derived bonding MOs (e.g., Figs. 10.21, 10.23, 10.25). The textbook treats all ligand bonding MOs as equivalent and assigns AOM stabilization energies for each by simply reading the values off the table at each ligand position. As we know, this is incorrect for symmetry reasons – six ligands in octahedral symmetry do not give six equivalent bonding MOs, nor can the bonding counterpart to an antibonding orbital level differ in irreducible representation! The approach we used in class and on problem set #3 is symmetry-correct and gives the appropriate energy level diagram, but it necessarily incorporates an understanding of symmetry behavior in addition to the parameterization in the AOM tables. The textbook approach, on the other hand, ignores symmetry; total energies compute correctly because the energy increments are additive, but the specifics of ligand-derived MO energetics are incorrect. For a more detailed discussion of AOM with technical references, see this article from J. Chem. Ed..

Week 7

For a re-grade request, attach a sheet noting exactly why you believe there was a grading error; do NOT write on the original exam copy. We reserve the right to review the entire exam if it is submitted for re-grading.

The final exam covers material spanning the entire semester. Approximately one-quarter of the marks are in one section consisting of nine short (single-page) questions on various topics treated over the semester; students will be able to choose any five of those questions to answer for credit, and, if more than five questions are answered, the best five marks will be counted toward the exam grade.

In preparation for the final exam, office hours will be held from the Wed to the Mon preceding the exam, as follows: Max on Wed, 11 Dec, 10am-noon and Thu, 12 Dec, 1-3pm, in C2 381; Prof. Lee on Fri, 13 Dec, 2-4pm, and Mon, 16 Dec, 1-4pm, in C2 382.
