Episode 16: Inside the Unit- Electrons
Episode Summary
Hey Chemistry Friend! In this episode of The Confident Chemistry Teacher Podcast, Chem walks you through her Electrons Unit — from the evolution of atomic models to light and energy calculations, and finally, electron configurations. You’ll hear how she sequences lessons, which labs and demos make the biggest impact, and how she builds connections between math skills, color emissions, and atomic structure. Whether you’re teaching high school Chemistry or honors-level students, you’ll get ideas to simplify your planning and make this concept-packed unit more engaging and hands-on!
In This Episode, You’ll Learn:
⚛️ Why Chem teaches atomic history here (instead of during the Atoms unit) to deepen understanding.
💡 How she introduces light and energy equations (c = λv and E = hv) using fireworks as the anchoring phenomenon.
🔥 Favorite labs like the Flame Test Lab using soaked coffee stirrers and the Spectroscope Lab for visualizing emission spectra.
🧮 Tips for tackling math struggles early, including calculator practice and spacing out light calculations for extra review time.
🧠 How to teach electron configurations using both orbital diagrams and periodic table patterns.
📚 Optional extensions for advanced students, like quantum numbers.

Teacher Tip of the Week 💬
“If you haven’t yet, invest in a classroom set of scientific calculators! Teaching the light equations gets so much smoother when everyone’s using the same model.”
