Curated OER
Electron Configurations and the Periodic Table
In this electron configuration and the periodic table learning exercise, students are given a periodic table with each element. Students write the theoretical electron configuration for each element based on the rules for filling...

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...
