In this activity, students will collectively build molecular orbitals for homonuclear diatomic molecules using balloons as models for atomic orbitals. This activity gets students up and moving and involved in the building of an MO diagram and allows for 3-D visualization of the core concepts of building molecular orbitals from atomic orbitals.
This literature discussion focuses on a 2022 Nature Comm paper looking at the reasons behind the pyramidal structures of tri-coordinate f-element complexes. There is plenty to discuss in terms of bonding and coordination geometries in metal complexes, and the effects of pressure on coordination geometry.
A guided inquiry activity for students to build the MO diagram for HF based on energetic and symmetry considerations. Students then compare their model to a standard MO diagram and examine what additional information a MO diagram conveys that the Lewis structure does not.
This Literature Discussion LO was created for the ACS Inorganic Chemistry Award Winners. Dr. Kit Cummins was the recipient of the 2023 Frederick Hawthorne Award in Main Group Inorganic Chemistry. This LO is based on a recent paper from the group of Dr. Cummins, entitled "Sustainable Production of Reduced Phosphorus Compounds: Mechanochemical Hydride Phosphorylation Using Condensed Phosphates as a Route to Phosphite", published in ACS Central Science, 2022, 8, 332-339.
Chip Nataro (Lafayette College) hosts a live discussion covering the favorite labs that people teach. The discussion somewhat evolved into a conversation on "so, you are teaching inorganic lab for the first time...what do you do?"
This literature discussion is based on a 2022 Science paper describing a series of dilanthanide complexes with exceptional magnetic properties due to the presence of metal-metal bonding. These molecules are the first reported species to feature direct bonding between two lanthanides! The paper contains ample material for discussion of molecular symmetry and bonding, oxidation states and electron configurations, and magnetism. The handout includes a description, glossary, discussion questions, and pre-class worksheet.
This literature discussion was written for a foundation-level inorganic chemistry course to accompany the material on Lewis structures. It utilizes a communication-length article on fluorine azide and fluorine nitrate. The assignment is divided into two parts: a set of questions for students to answer BEFORE they read the communication and then a set of questions that they answer after reading the article.
This LO is a literature discussion based on one figure in Chan et. al.
The second 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.
We have developed a tabletop game to help students get comfortable with symmetry adapted linear combinations of orbitals (SALCs), a conceptual model used to understand bonding in molecular orbital theory. We have found that students often get anxious about SALCs and miss not only the visual connections to symmetry, but also the fun! This LO includes information about the game, files you can use to print your own copy as well as a link in case you want to purchase a copy, and an example of how it might be incorporated into the classroom.
