Using Computational Chemistry to discuss backbonding to CO

Submitted by Lori Watson / Earlham College on Sun, 03/08/2009 - 15:01
Description

This activity uses Gaussian with the WebMO interface to investigate the role of the metal in backbonding to CO as well as effects of the trans ligands. It can also be used as a way of introducing computational chemistry in an inorganic course.

Polarizing Power of Cations

Submitted by Nancy Williams / Scripps College, Pitzer College, Claremont McKenna College on Tue, 02/24/2009 - 20:08
Description

This is a handout which I use in an advanced general chemistry course, but which could be used in an inorganic course as well. It is a mini-periodic table with common cations and their charge to size ratios expressed as Q/r2, where Q is in integer charges (+1, +2), and r is in Angstroms. Conveniently, Na+ is an easy to remember 1.0, and Al3+ and Be2+ are easy to remember values of 10. This corresponds to the polarizing power of these ions, and is a crude proxy for how covalent their interactions with a given anion tend to be.

Citing and Finding Chemical Literature Library Activity

Submitted by Jezmynne / Claremont University Consortium on Tue, 02/24/2009 - 18:45
Description

This assignment will orient new students to searching and finding chemical literature and effectively citing said literature.  The library session focuses on the semantics of the ACS style, overviews appropriate indexing/searching tools, and has students search and find two citations for a future lab assignment for their chemistry class.

Description

Delicious is a social bookmarking tool that retains bookmarks on the web.  Users can access their bookmarks from any computer, and Delicious allows for the tagging of bookmarks with relevant descriptors for follow up, searching, and collaborative work.  

Contemporary Inorganic Chemists

Submitted by Betsy Jamieson / Smith College on Tue, 01/13/2009 - 11:59
Description
This is an assignment I use to give students a sense of what kinds of problems real life, contemporary inorganic chemists work on.  I start out by having them find 2 contemporary inorganic chemists.  They give a 15-20 min presentation on their two chemists that gives a general overview of their research projects.  Once everyone has done their general presentation, I have students choose a specific journal article by one of their chemists to present in class.  I usually have this assignment run throughout the semester, with the general presentations taking place in the first half of the semeste

Inorganic Chemistry Just Makes You Want to Sing!

Description

Here is a fun way to learn about inorganic chemistry!  These songs were composed and passed along to me by Tom Mallouk at Penn State with his permission to post here on VIPEr.  I Can't Get No Bragg Diffraction was a joint effort put together one year at a Gordon Research Conference on Solid State Chemistry.  Sorry, no recording!  The tune n-doped, recorded by the Band Edges, covers the electronic structure behind semiconductor devices.  Download the lyrics for both and the mp3 file for n-doped!  There is a

Assessing Chemical Hazards

Submitted by Anne Bentley / Lewis & Clark College on Tue, 10/14/2008 - 20:17
Description

This is a short activity I developed to help my students interpret Material Safety Data Sheets (MSDS). Students rank unknown compounds from least safe to most safe, and the compounds' identities are revealed. The class discusses other factors to consider in evaluating the safety of an experiment. The "MSDS activity" word document contains a more full description.

Aufbau Exercise

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 10:12
Description

This is a Challenge for the beginning of an Inorganic class, to remind students of the basics of Aufbau, etc. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games. You can pick and choose Challenges from our Web site to increase active learning in your classroom, and we ask that you contribute creative Challenges of your own to give a head start to teachers at other colleges and universities!

Point Group Symmetry Game

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 09:59
Description

This is a game that gets students interested in point group symmetry, and helps them to see the symmetry in everyday objects. It is a competition in which the groups try to bring in the hardest object to assign. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.

Werner's Nobel Prize Address

Submitted by Maggie Geselbracht / Reed College on Wed, 04/02/2008 - 02:54
Description
Alfred Werner's Nobel prize address in 1913 offers a unique historical view on the development of coordination chemistry from the expert. With a bit of "translation" to modern terminology, this paper is very accessible to most students. Discussion of the address provides a useful introduction to coordination complexes including structure, isomers, and ligand substitution reactions.
