• The air contains around 78% nitrogen, 20% oxygen, and 1% water vapor which varies from place to place.
• Argon, helium, neon, argon, krypton, xenon, and radon makes up the most of the remaining 1% (0.97%), with carbon dioxide only around 0.03%.

Part 2: Uses of Noble gas

• Helium is a noble gas that is used to fill weather balloons.
• Argon is a noble gas that is used to fill electric lights at low-temperature.
• Neon is used to make advertising light tubes that may be seen at night in huge stores, hotels, and other places.
