Compared with solids and liquids, how is the density of a gas?
- Much higher
- About the same
- Highest of all

Gas particles are far apart, so a gas has a low density.
Which of these noble gases is very light and is often used to fill party balloons?
- Chlorine
- Helium
- Oxygen
- Nitrogen
Show answer and solution
Correct answer: B. Helium
Helium is a noble gas, meaning it is a single atom gas that does not react easily, and it is light.
