Examining and Drawing Atomic Orbitals
This exercise makes use of a web-based tool to review quantum numbers of the orbitals of the hydrogen atom and to visualize atomic orbitals in 3D. Students are asked to draw the 1s-, 2p- and 3d-orbitals.

This is an in-class discussion of an article that appeared in The Economist. It can be used to review several topics covered in the first year chemistry class.
This excercise explains the basics of drawing graphs for an introductory chemistry class. It give examples of common pitfalls and how to avoid them. Students are guided through graphing a data set, adjusting axes, adding trend lines, modifying legends and adding appropriate labels. The excercise also provides several examples of graphs and asks students to critically evaluate them.
This is an in-class activity that I made to help students in my second semester general chemistry course work through some aspects of color and coordination chemistry. The activity was performed with a demonstration of color for nickel coordination complexes (ligands: water, ethylenediamine, and ammonia). I also included equilibria and thermodynamics as those concepts apply to coordination compounds at the introductory level. This served as a review of the concepts as well.
While informally chatting with friends in our math department, I realized that I could put together a presentation about how chemists use group theory. I was invited to give the presentation as part of our math department's weekly colloquium series. The talk was to be one hour in length, and my math colleague described their typical format as:
Every day when I teach Inorganic Chemistry (and in most of my problem sets and take home exams) I create Web pages to show 3D images of selected molecules to my students. I am a visual learner and I find the structures beautiful and informative.
In the past few months, you likely have found that web sites scripted with Jmol scripts calling a Jmol applet (which is a Java applet) are blocked.
Students construct computer models of two transition metal complexes, solve their electronic structures, and inspect the resulting d-type molecular orbitals to identify which are non-bonding, sigma* antibonding, or pi* antibonding. After constructing a molecular orbital diagram, they determine which of the two complexes is likely to absorb light at a longer wavelength.
Description: This is an in class activity I use for first year general chemistry students to understand the relationship between quantum numbers and the structure of the atom.
This in-class activity is intended to help visualize the meaning of the subscripts and coefficients in molecular formulas that appear in balanced chemical equations. It has been my experience that students in 2nd semester general chemistry can sometimes still be confused about this fundamental aspect of chemical language. It substitutes edible candy for the atoms in a molecular model kit, thus allowing students to eat the atoms at the end. (My philosophy is that if students are eating, they're probably awake and could be learning!)
I modified the Barb Reisner/Joanne Stewart/Maggie Geselbracht First Day TOC activity (https://www.ionicviper.org/class-activity/introducing-inorganic-chemist…) to take advantage of the quarterly list of Top 10 Most Read articles that IC sends out. This is delivered to me as an email from ACS pubs and I am sure that it is available to anyone who wished to subscribe to the updates. I have attached a pdf copy of the August 2013 update as an example.
