Group 0 elements

Question 1

What are the group 0 elements

Answer 1

called nobles gases
They are helium, neon , argon
8 electrons in outer shell apart from helium with 2 electrons on its outer shell giving them a full outer shel
As their outer shell is energetically stable they don’t need to give up or gain electrons to become stable - they don’t react with much

2) they exist as monatomic gases - single atoms not bonded to each other
3) colourless gases at room temperature
4) inert so non flammable

Question 2

Properties of noble gases as you go down

Answer 2

bp increase while RAM increases

Increase in bp is due to increase in number of electrons in each atoms leading to greater intermolecular forces which need to be overcome.
