Exist as monatomic gases (single atoms not bonded)
All Group 0 elements are colourless gases at room temperature
Group 0 elements are non-flammable
As you move down Group 0
The boiling points of the noble gases increase
The increase in boiling point is due to an increase in the number of electrons in each atom, leading to greater intermolecular forces that need to be overcome
Noble gases
Helium
Neon
Argon
Krypton
Xenon
Helium has a lower boiling point than neon as it is further up the group
Xenon's boiling point
Is between radon and krypton
The actual boiling point of xenon is around -108°C
Noble gases don't really react, so there isn't too much to learn about them
Argon is very unreactive
Argon's unreactivity is due to its electronic structure having a full outer electron shell
