From Whiteboard to Spartan: An Integrated Exploration of H2A Molecular Orbitals and Molecular Geometry
Description

This two-part activity offers an integrated approach to understanding molecular orbitals and molecular geometry. In class, students will first engage in a hands on, qualitative construction of the H2O molecular orbital diagram using symmetry principles and a whiteboard.

Exploring the Electronegativity and Hardness of the Noble Gases

Submitted by James F. Dunne / Central College on Fri, 02/21/2025 - 11:15
Description

This is a literature discussion focused on calculating and comparing the Mulliken electronegativites of the noble gases. Students can explore how this periodic property extends into the noble gases and impacts the observed reactivity of Group 18 compounds.  The discussion could be used either as an in-class activity or a homework assignment.

Replace the Orbitron
Description

There are several LO's on the site that use the Orbitron which unfortunately is no longer available. Here is another option that should allow use of those LO's.

Moleculuar Computation and Visualization in Undergraduate Education (MoleCVUE)
Description

The MoleCVUE website contains several items that should be of interest to the VIPEr community, especially the activities.  Each activity is designed to be ready to deploy in lecture, laboratory, or as homework.  There are activities covering all of the major subdisciplines of chemistry (some more than others).  Some activities that might be of particular interest to VIPEr are "Group Theory", "VSEPR", and "Electron Configurations of Atoms and Ions".  All of the activities are written to use WebMO, but could be adapted for other systems.  Most activities are doable with the free or demo versi

Atomic Orbital Representations and the Orbitron
Description

This POGIL based activity is intended to review general chemistry concepts of atomic structure and to further those concepts with additional attention to d orbitals and radial distribution graphs.  The primary model in the activity is The Orbitron website (https://winter.group.shef.ac.uk/orbitron/) with students examining the isosurface and radial distributions for a variety of orbitals.

Phosphate Reduction by Mechanochemistry (Cummins)
Description

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 Science20228, 332-339.

Introduction to Borane and Carborane Clusters: Practice with Point Groups, Electron Counting, and Electronegativity with Computational Support
Description

This LO uses borane and carborane clusters to practice assigning point groups and counting electrons. It also asks students to recall electronegativity trends to predict dipoles, and they can check their predictions against calculated Mulliken charges.
