  2. Nitrogen (N2): fire suppression, provides an inert atmosphere
  3. Helium (He): balloons, medical equipment 
  4. Argon (Ar): welding, provides an inert atmosphere for materials
  5. Carbon dioxide (CO2): carbonated soft drinks
  6. Acetylene (C2H2): welding 
  7. Propane (C3H8): fuel for heat, gas grills
  8. Butane (C4H10): fuel for lighters and torches
  9. Nitrous oxide (N2O): propellant for whipped topping, anesthesia
