Description: 

This set of slides was made for my Organometallics class based on questions about bridging hydrides and specifically the chromium molecule. I decided to make these slides to answer the questions, and do a DFT calc to show the MO's involved in bonding of the hydride. 

 

Corequisites: 
Learning Goals: 

A student will be able to explain bridging hydride bonding

A student will be able to perform electron counting on a chromium comples with a bridging hydride

A student will be able to interepret calculated DFT molecular orbitals. 

Time Required:

Quantum Numbers and Nodes

Submitted by Jack F Eichler, University of California, Riverside
Evaluation Methods: 
1) Performance on the pre-lecture online quiz

2) Performance on the in-class activity (clicker scores or hand-graded worksheet)

 

 

 

Evaluation Results: 

Students generally score on average 70% or higher on the pre-lecdure quiz, and on average 70% or more of students correctly answer the in-class clicker questions. 

Description: 

This is a flipped classroom module that covers the concepts of quantum numbers, and radial and angular nodes. This activity is designed to be done at the beginning of the typical first quarter/first semester general chemistry course (for an atoms first approach; if instructors use a traditional course structure this unit is likely done towards the middle/end of the first quarter/semester). Students will be expected to have learned the following concepts prior to completing this activity:

a) quantization of energy in the atom and the Bohr model of the atom;

b) how the wave/particle duality of electrons was described by de Broglie;

c) how the wave/particle duality of electrons was used by Schrodinger to develop the quantum mechanical model of the atom;

d) how radial probability distribution was used to generate the idea of atomic orbitals, and orbital probability surfaces.

Learning Goals: 

a) describe the meaning of the quantum numbers n, l, and ml;

b) determine the values of the quantum numbers n, l, and ml;

c) describe the meaning of radial and angular nodes;

d) determine the number of radial and angular nodes on different types of atomic orbitals;

e) begin to understand the correlation between the quantum numbers and the total number of atomic orbitals for a given atom, and how the periodic table can be used to build up the overall orbital structure for an atom.

 

Equipment needs: 

Suggested technology:

1) online test/quiz function in course management system

2) in-class response system (clickers)

5-ish Slides about Enemark-Feltham Notation

Submitted by Kyle Grice, DePaul University
Description: 

This is a basic introduction to Enemark-Feltham that can be used in conjunction with any literature that has Iron nitrosyls in it. I made this as a follow up to the work that came ouf of the 2018 VIPEr workshop in UM-Dearborn. 

Corequisites: 
Learning Goals: 

A student will be able to detemine the Enemark-Feltham label for a simple iron nitrosyl

A student will be able to describe bonding differences between NO+, NO, and NO- ligands. 

Implementation Notes: 

I haven't used this yet, but It can be a quick lecture module or online module to help students understand Enemark-Feltham before analyzing a paper on iron nitrosyls. 

Time Required: 
10 min
