Topic Summary: Group 0 Noble Gases
Key Terms
- Noble gases: Group 0, full outer shells, unreactive
- Inert: Unreactive (old term)
- Monatomic: Exist as single atoms
- Full outer shell: He = 2 electrons; others = 8 electrons
Must-Know Facts
- Unreactive because outer shell is full
- Helium: 2 outer electrons (not 8)
- Monatomic — no bonds between atoms
- Helium → balloons (light, non-flammable)
- Neon → signs (glows in electricity)
- Argon → light bulbs and welding
- Boiling point increases down the group
