Electron Configuration Practice for the First 20 Elements
A practice set for 9th graders on writing and drawing electron configurations for elements 1 through 20 using the Bohr model and shell notation. It builds skills in reading atomic numbers, filling electron shells in order, and translating shell notation into diagrams, and it opens with a key-terms callout covering atomic number, electron shells, and shell notation.

Teacher Guide & Tips
- Use this as a 30 to 45 minute guided practice following an introduction to the Bohr model, or as independent work once students have seen a worked example of shell filling.
- Discussion question: Why does the first shell hold only two electrons while later shells hold more, and how does that pattern explain why elements in the same column behave similarly?
- Scaffold for struggling readers: Have students build the first five elements with physical or paper counters before drawing, and keep the key-terms callout visible as a reference.
- Extension for advanced students: Ask them to predict the configuration of an ion, such as Na+ or Cl-, and explain how the charge changes the shell arrangement.
- Estimated time: about 30 to 45 minutes for the full set, with extra time if students are drawing each diagram by hand.
