Ionic Bonding — Electron Transfer
Description
Visualizes ionic bonding by showing how sodium donates its single valence electron to chlorine. The resulting oppositely charged ions attract each other to form NaCl. Electron shell diagrams and LaTeX equations are shown at each step.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Title | ~3s | Title appears |
| 2 | Na atom intro | ~5s | Na Bohr model shown, 11 electrons labeled, valence electron highlighted |
| 3 | Cl atom intro | ~5s | Cl Bohr model shown, 17 electrons labeled, 7 valence electrons highlighted |
| 4 | Electron transfer | ~7s | Valence electron animates from Na to Cl; Na becomes Na⁺, Cl becomes Cl⁻ |
| 5 | Equation display | ~4s | MathTex equation shown |
| 6 | Ion attraction | ~6s | Na⁺ and Cl⁻ move together, + and − charges shown |
| 7 | NaCl crystal | ~5s | Ions merge, "NaCl" label appears |
| 8 | Outro | ~3s | Summary text |
