What are group 0 elements called
Noble gases
Name the noble gases
-Helium -Neon -Argon -Krypton -Xenon -Radon
Properties of noble gases
-Colourless gases at room temperature -Monatomic -Inert -Non-flammable
Monatomic
Made up of just single atoms
Inert
Don’t react much at all
Why are noble gases inert
They have a full outer shell
Why are noble gases non-flammable
They are inert so won’t set on fire
Why did it take a while to discover the noble gases
Their properties made them hard to discover
What is the significant property about noble gases which enables them to have many uses
They are inert
Use of argon
-Filament lamps -Flash photography -Protecting metals being welded
Why is argon used in filament lamps
It is non-flammable so stops the very hot filament from burning away
Use of krypton
Flash photography
Use of xenon
Flash photography
Why are noble gases used in flash photography
They stop the flash filament from burning up during the high temperature flashes as they are inert
Use of helium
-Protecting metals being welded -Airships -Party balloons
Why are noble gases used to protect metals being welded
Their inert atmosphere stops the hot metal reacting with oxygen
Why is helium used in airships and party balloons
-It has a lower density than air so it makes the balloon float -It is non-flammable so it is safer to use than hydrogen gas
Trend in properties of the noble gases
Boiling point, melting point and density increase down the group
