Orbital Diagrams
Use this set of slides to demonstrate how to draw orbital diagrams for different atoms. The first slide provides a few tips, and the next three provide examples. Finally, learning check slides give viewers an opportunity to put into...
Curated OER
Subshells and Orbitals
Electron energy levels are introduced to aspiring chemists in this PowerPoint. The number of electrons allowed in each level is explained, and then viewers learn how to write the electronic configuration of an element based on this...

Electron Configurations and the Periodic Table
In this electron configuration and the periodic table instructional activity, students are given a periodic table with each element. Students write the theoretical electron configuration for each element based on the rules for filling...
Curated OER
Shells and Subshells
Students explore how to show evidence of subshells and electron filling on the visual scale. They examine subshell filling and evaluate unknowns based on the atomic emission spectrum. Students design an experiment to identify colors of...
