halogens have relatively low melting and boiling points that increase steadily down the group. near room temperature halogens span all of the physical states.
all noble gasses conduct electricity, flouresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant enviroment.
