Chemical structure of group 0

monatomic

Uses of helium

Balloons and airships, because it floats on air

Uses of Argon

In filament bulbs and shield gas in welding because it is inert and more dense than air

Uses of krypton/

Used in light bulbs as it is inert and stops the filament burning away
