Helium
neon

How many electrons do they all have on there outer sheLl
8 = full shell

What do they exist as
Monatomic gases -single atoms not bonded together
What do they all appear as at room temperature
Colourless gases
Why are they all nonflammable
Because they are inert
Patterns of the properties of noble gases
Bp increase as you go down
Why di the boiling points of the noble gases increase as you go down
Due to the increase in the number of electrons in each atom leading it to have greater intermolecular forces that need to be overcome
