Jahn-Teller effect, theory and examples

Submitted by Adam Johnson / Harvey Mudd College on Thu, 08/06/2020 - 18:44
Description

At a recent SLiThEr workshop, a request was put out for an introduction to the Jahn-Teller effect. I had already prepared several slides showcasing single crystal X-ray data for my class this spring so I put this together with some additional examples from my lab and the literature.  Single crystal XRD data is presented to support the claims.

ChemCrafter

Description

ChemCrafter, from the Science History Institute (formerly the Chemical Heritage Foundation), is a free iPad app that mimics a classic chemistry set. It is set up as a game, with three sections: reactions with water, reactions with acid, and salts. The app shows the progress of the reaction (smoke, color change, etc.) when two elements are mixed in a reaction vessel, and also gives the change in enthalpy of the reaction.

Advanced Inorganic Chemistry
Description

Many of the topics in this course have their origins in the topics that are covered in General Chemistry but are covered in more detail.  Many of the rules learned in General Chemistry are actually the exception.  Chemical systems are much more complicated than the simple models presented in a first year course.  The course begins with the electronic structure and periodic properties of atoms followed by discussion of covalent, ionic, and metallic bonding theories and structures.  Students also apply acid-base principles to inorganic systems.  The second half of the course is dedicated to t

2019 Nobel Prize - Li-ion battery LOs

Submitted by Barbara Reisner / James Madison University on Wed, 10/09/2019 - 20:28

Congratulations to the 2019 recipients of the Nobel Prize - John B. Goodenough, M. Stan Whittingham and Akira Yoshino. It's a well deserved honor!

There are several LOs on VIPEr that talk about lithium ion batteries and related systems. The 2019 Nobel is a great opportunity to include something about these batteries in your class.

I hope to see more LOs in the coming weeks so we can bring this chemistry into our classrooms!

This second semester general chemistry course is a continuation of the Principles of Chemistry sequence that is recommended for science students. The focus of the course is the fundamentals of structure and bonding, with an emphasis on predicting reactivity.

VIPEr Fellows 2019 Workshop Favorites

Submitted by Barbara Reisner / James Madison University on Sat, 06/08/2019 - 16:41

During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.

Helping Students with Visual Impairments See Colors

Submitted by Doug Balmer / Warwick High School on Fri, 05/31/2019 - 12:05
Description

I have had some students in class have a hard time identifying colors (flame tests, solution color, acid-base indicators, etc.) because of a visual impairment. There are many cell-phone apps that are helpful in aiding these students. "Pixel Picker" allows the students to load a picture from a device (cell phone, ipad). This is helpful because students are now dealing with a "frozen" image. Moving the cross-hair to different parts of the picture changes the R-G-B values. The "Color Blind Pal" app uses a more qualitative approach.
