1. Bonds cut-and-paste activity 2-3L

2. Use a white or light colored letter size paper.
Fold it twice to get 4 equal areas.
Top two areas: Draw atom models for Na, and F
Bottom two areas: Draw atom models for F, and F

5. Adding electrons
Make electrons by punching red paper. Each red dot represents an electron
Paste electrons in the atoms, following the electron config (1s2, 2s2, .. etc.)
Intentionally, do not paste any electrons that need to be “lost”
Intentionally, leave a blank space where you are going to gain electrons.

6. Making stable configs. All your atoms want to be perfect octets.
Demonstrate Na becoming an octet
Demonstrate F becoming an octet
Bottom 2 F’s: How do these become octets?
