Group 0 - Noble Gases Flashcards
What are the first 4 elements and their symbol
Helium
Neon
Argon
krypton
What does all the group 0 elements look like at room temperature
Colourless gases at room temperature
The noble gases are all monatomic, what does monatomic mean?
The gases are made up of single atoms
What is the word that describes the gases don’t react much
Less inert
The gases are less inert, why don’t they react?
The have a full outer shell of electrons - they don’t give up or gain electrons
What is a good property about noble gases
The gases are non-flammable so they won’t set fire
What can noble gases be used to provide
They can be used to provide an inert atmosphere
What is the use for argon
Used in Filament light ( blue light ) - this helps filament from burning away
What is uses krypton, argon and xenon
Used to stop the flash filament from burning up during high temperature flashes
What can be used using Helium and Argon
They can protect metal from welding - this stops the hot metal reacting with oxygen
What is the use for helium
It is used it airships ( non-flammable )and PARTY BALLONS ( lower density than air = float )
Properties of noble gases
Boiling points, melting points and density all increase as you go down the group
The elements will react in similar ways because they have the same number of electrons in outer shell
