   As I recall, that would be a tall skinny tree! The two largest members of the group have electrons so far out from the nucleus, that Fluorine can entangle them, forming genuine compounds, with actual medical uses as toxic to viruses. Two compounds each? Haven't heard of anything like that. But I haven't looked lately, either! Regards, Larry.

   He and Ne form NO stable compounds but He can form some unstable compounds in certain extreme conditions (in a gas discharge tube where a high voltage current is run through the tube). Ne only forms unstable ions (i.e Ne+ or NeHe+ etc.) and no unstable compounds.

   Argon forms compounds at ultralow temperatures, for example the first argon compound formed was Argon Hydrofluoride is stable at temperatures up to 40K (-233 degrees Celcius).

   Starting at Kr and on down the comlumn you start seeing room temperature stable compounds with the halogens and other various species (i.e. XeF2 etc.)

   A good is google. Start looking for Compounds containg _____ followed by the element name (i.e. Krypton).

   Wikipedia also will be a good STARTING/CONFIRMING resource but is not a good primary source (i.e. you won't cite it but instead use it to find sources you CAN cite).

   you find the elements that are related to each other like your family.
