In this activity, students construct molecular orbital correlation diagrams for several species (H2, He2, HeH), in a semi-quantitative fashion using a ruler and a list of first ionization energies. All the MO schema are placed on a common energy scale, and the stability of each orbital is reported using "cm from the top of the paper" as the unit of energy.
In this in-class activity, students are broken up into teams of 4, which are then sub-divided into two teams of two for the building of the structures. The activity makes use of the ICE Solid State Model kits, and each group should have their own full kit.
The activity has 6 sets of structures for the teams to build; depending on the length of your class, you could have each team build all six sets OR have each team build one of the six sets to then share with the rest of the class.
A - HCP and CCP
B - Primitive cubic and CsCl
This is a jmol display of the atomic orbitals from 1s to 4f that can be rotated in space. They are plotted relative to the x, y, and z-axes.
Recent versions of Wolfram's Mathematica software have access to a variety of curated data sets that are relevant to Chemists. This activity is an example of how one can use the ElementData dataset to develop an on-line tool to explore periodic trends. Wolfram provides a free web-based platform (the FreeCDF plugin) to view and interact with specifically designed Mathematica files. The activity can be accessed in one of three ways:
I found this great website linked from somewhere a few days or a week ago and already forgot where. But I am teaching organic lab this semester and convinced one of the students to do a little research. As a reward, I am going to buy her, and the whole class, gelly roller pens for keeping their notebooks.
This is a GREAT site that has so much detail on keeping a lab notebook. There is a lot of great stuff in there.
This is an in-class activity--or an activity students do prior to class to in preparation for an in-class discussion--to help students identify stylistic components of published writing. I provide the students with an appropriate journal article, typically a communication from Inorganic Chemistry, such as Inorg. Chem. 2008, 47, 2922-2924 (http://pubs.acs.org/doi/pdfplus/10.1021/ic702373b) or Inorg. Chem.
This lecture provides a short introduction to the other half of biological iron chemistry: enzymes that do not contain a porphyrin group that ligates the iron atom. There are several important applications for non-heme iron in cells, both mammalian and bacterial. Oxygen activating non-heme iron enzymes fall into a few basic categories and includes mononuclear iron monooxygenases and dioxygenases, and binuclear iron monooxygenases. The requirements to activate and utilize dioxygen will be given.
These slides provide a brief introduction to the concept of electrocatalysis using the glyoximato cobalt catalysts for hydrogen production recently examined by Peters, Gray, and others. They provide a suitable introduction to the topic for students interested in reading the primary literature on these topics.
I am always interested in building/modifying equipment and glassware, and the following C and E News article led me to an interesting website, also linked, where details on building homemade rotators and stir plates are in place. Both models can be constructed with materials for less than $30. As I'm always looking to keep costs down for equipment like this, I thought I would share it. If anyone knows of other links, please let me know.
I learned of this website after attending the Computational Chemistry for Chemistry Educators (CCCE) workshop last summer '11. In this webpage you will find all the workshop lectures intended for audiences who do not have a computational expertise. You will also find lab exercises already written.
