Rank from most to fewest valance electrons

The question is not clear. Do you mean what's the maximum amount of valence electrons a shell could hold? If that's what you meant then the first shell can hold 2, the second can hold 6, the third can hold 8. If you're in University then the answer would be different however.

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other
