d-orbitals in a variety of ligand geometries

Submitted by Flick Coleman / Wellesley College on Fri, 03/13/2009 - 20:54
Description

I developed this Jmol page to help my students see the relationship(s) between the ligands and metal d-orbitals in a number of different geometries.  Since the images are all rotatable, students who have difficulty looking at flat images and drawing appropriate conclusions have that barrier reduced or eliminated.  I have now used the application twice - this past fall in the second semester of introductory chemistry and a few weeks ago when I began ligand field theory in my inorganic course.  In both classes I received favorable comments.  A number of students in the inorganic course, who h

Interactive Spreadsheets for Inorganic Chemistry

Description

This web site contains a number of interactive spreadsheets, most of which are applicable to inorganic chemistry (or a physical chemistry class that uses inorganic examples).  Here's the list of the most relevant for most inorganic classes:

 

ABC kinetics - interactively plot concentration versus reaction extent for A, B and C in A -> B -> C by varying k values

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.

Oliver Sacks' "Uncle Tungsten" and inorganic chemistry

Submitted by Joanne Stewart / Hope College on Fri, 07/18/2008 - 21:32
Description

Students read Oliver Sacks' autobiography "Uncle Tungsten" and take turns writing chapter summaries and discussion questions. Some chapters focus on Sacks' childhood chemical explorations and others on the historical period of his youth. In the summary, students are asked to either explain the chemistry in contemporary terms OR explain the context (what was going on in the world) of the historical pieces.

What happens when chemical compounds are added to water?

Submitted by Barbara Reisner / James Madison University on Sat, 11/17/2007 - 18:38
Description

It’s very surprising how little students remember from general chemistry.  This assignment helps students make connections between the macroscopic properties of solutions and what happens at the molecular level.  This activity serves as a bridge between sections on acid-base chemistry and coordination chemistry.

Students are solicited for their models of the behavior of different chemical compounds in water in class and asked to put these models on the board.  We then look at the properties of these solutions (color, acid-base) and refine these models in class.
