One of my questions asks me to find the volume of neon gas. I thought neon didn't attach with other atoms because it had a full valence shell, how would it form into a gas? What would the formula be? N2, N3 ?

Neon IS a gas and it doesn't form compounds if that is what you mean by attaching itself to other atoms. There must be more to the question than simply what volume. Are there several volumes? change of temperature? change of pressure? Post the entire question and we can help you through it.
I think I understand it now. They also said at STP. I didn't notice that at first. Thanks :)
