Bohr Models & the Periodic Table — Interactive (GSE 1.4b)

8th Grade Physical Science | Drag‑and‑Drop • Dropdowns • Graph • 5 Milestones‑style items
Reading Quick Notes

Bohr models show electrons in energy levels (shells) around the nucleus. The first shell (K) holds up to 2 electrons, the second (L) up to 8, and the third (M) up to 18 (commonly shown as 8 for main‑group elements).

On the Periodic Table, a period is a row (left → right) and a group is a column (top ↓ bottom). Elements in the same group share valence electron patterns and similar chemical properties.

Across a period, atomic radius generally decreases, while ionization energy generally increases. Down a group, atomic radius generally increases.

A Match Elements to Bohr Models
