noble gases in group 18

The noble gases do not form chemical bonds because all of their shells are filled. When a noble gas does not form that is because all of their shells are filled and don't need any other element. All of them in group 18 are the same. Since they are all the same they do not need no other element. They can only combine with each other and that is why they are a group.

Solids, Liquids, and Gases

Depending on where the gas, liquid, or solid is that is how it will racket. It can be a tight place so the liquid would still move fast but not as fast as we would like it to go or as fast as it can go. Where the matter is that is how it will move. Gas is a very fast property but if it is in a small container it is not going to go as fast as it really does. Depending in where the property is depends on how it moves.

It is a physical change because the color changed over time. If it was a chemical change then the Statue of Liberty would have changed completely and it did not just the color and there for it is a physical change
