2023 Content Building Workshop - Morgan State University

Submitted by Chip Nataro / Lafayette College on Tue, 06/27/2023 - 10:56

This is a list of all of the learning objects developed in association with the 2023 content building workshop. Prof. Robert Gilliard was the featured speaker for this workshop, so most of the LOs will focus on his work.

Examination and Classification of Molecular Symmetry
Description

This is a hands-on introduction to molecular symmetry and point groups. Students are not expected to have any exposure to molecular symmetry before this lab. Students work in pairs to identify symmetry elements in molecules and assign molecules to appropriate point groups.

Balloon Built Molecular Orbitals
Description

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.

Inorganic Chemistry Laboratory

Submitted by Cody Webb Jr / Hartwick College on Wed, 06/14/2023 - 02:02
Description

Students perform weekly laboratory experiments to explore and apply concepts covered in the lecture
component of the course.

Inorganic Chemistry I

Submitted by Cody Webb Jr / Hartwick College on Wed, 06/14/2023 - 01:57
Description

This course focuses on the chemistry of the elements, including electronic structure, bonding and
molecular structure, ionic solids, coordination compounds, the origins of the elements, and the descriptive
chemistry of the elements. Topics also include inorganic synthesis, materials science, industrial chemistry,
and an introduction to bioinorganic chemistry.

Materials Chemistry

Submitted by Deborah Polvani / Washington & Jefferson College on Mon, 06/12/2023 - 09:33
Description

Materials Chemistry will explore many of the fundamental relationships between a material’s chemical structure and the subsequent interesting and useful properties that result.  In order for advances in electronic, magnetic, optical, and other niche applications to be made, an understanding of the structure-property relationship in these materials is crucial.  This course will emphasize inorganic systems, and topics will include descriptions of various modern inorganic solid-s

Atomic Orbital Representations and the Orbitron

Submitted by Andrea Van Duzor / Chicago State University on Fri, 06/09/2023 - 16:37
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.

Synthesis and Characterization of Aluminum Complexes of Redox-Active Pyridyl Nitroxide Ligands (Graves/Schelter)

Submitted by Shirley Lin / United States Naval Academy on Mon, 05/08/2023 - 08:32
Description

This literature discussion focuses on a Inorg. Chem. article that describes a series of Pt complexes that exhibit competitive reductive elimination reactions to form either an sp2-sp3 bond or an sp3-sp3 bond. One of the complexes also contains a C-C agostic interaction with the metal. The questions are written to be addressed by students in a foundation-level inorganic course.

Zr/Hf Polyoxocation Chemistry (Nyman)

Submitted by Hilary Eppley / DePauw University on Mon, 03/20/2023 - 20:37
Description

In fall 2022, May Nyman from Oregon State was awarded the F. Albert Cotton Award in Synthetic Inorganic Chemistry for her outstanding accomplishments in synthesis and development of polyoxometalates and metal oxohydroxoclusters, including their structures, speciation, reaction mechanisms, and function. In this literature discussion, students will examine her recent paper “Differentiating Zr/Hf Aqueous Polyoxocation Chemistry with Peroxide Ligation," Inorg. Chem. 2021, 60, 1631-1640 which is related to that work.
