Monatomic nature of noble gasesNoble gases are monatomic. This means they exist only as single atoms. Their atoms cannot combine with other atoms because in their electronic structure, the outer shell is always full and this makes noble gases unreactive
Argon
Light bulbs
Doesn’t react with the metal filament
Helium
Used with O2 for deep sea dives
Low solubility of helium in the blood.
Helium
To inflate the tyres of large aircraft
Non-flammable
Helium
To fill airships and weather balloons
Low density, does not burn
Uses and properties of noble gases
Neon
In advertising signs because it glows red when electricity passes
Conductor of electricity at high voltage
Krypton/Xenon
In lamps used in photographic flash units, in stroboscopic lamps used in lighthouses
Gives out a lot of light when electricity passes through
