Helium is a very light gas and is used in hot air balloons or weather balloons.
Plants use nitrogen in the form of nitrates from the soil and nitrogen is important to animals for their growth and development.
Neon is used in signboards as it glows with a distinct and bright colour when electricity is passed through it.
A thin metal filament like tungsten inside the bulb would react with oxygen and burn away if the bulb is filled with air instead of argon. Argon stops the filament to burn away because it is unreactive.
