I am sorry that I was not making my point clear
What is there about He Ne Ar that is different than H2 O2 N2
Ahh, He, Ne and Ar are all noble gasses, meaning the outershell is full, therefore it is extremely difficult to make them react unlike oxygen, nitrogen, etc.
I'm guessing what you're getting at is, He is just He on it's own as a gas, because it doesn't need to react with any other substance.
I totally forgot about this. Hehe guess i need to go back to the basics if I want to be fully prepared for Unit 3/4 Chem.
I've said this a lot, but thanks again for the help. Really appreciate it
