Ek!

My teacher gave me a bunch of cards with fake names all with atomic weight boiling point if its a conductor & which cards it bonds with. So I need to group these. I started by putting them in order by their weight. Then I made groups by seeing which ones are non conductors semi conductors & conductors. & There's cards which form no molecules to I assume those are the ''Noble Gases'' but how can I break the groups down further by seeing who they bond with? My teacher showed me this, but I dont understand whats happening in the picture & how does it help me break down the groups. Can anyone help please?
