chemical and physical properties?
what do all the elements have in common? what trends are within the group in terms of reactivity or other properties? (do not simply list detailed properties of individual elements) *** talking about noble gases***

in common: They all have a filled valence shell and are very non-reactive. They are all gases.
You can get some of the larger ones in the group to react and form compounds with oxygen and fluorine. So, reactivity would generally increase going down the group.
