📌 Properties of Noble Gases
All noble gases are:
- Colourless gases at room temperature
- Monatomic — exist as single atoms (He, Ne, Ar), not molecules
- Very unreactive — don't form compounds naturally
- Non-flammable — won't catch fire
Trends down the group:
- Boiling point increases (He: -269°C → Rn: -62°C)
- Density increases
