what is so special about the elements in Group 8 on the Periodic table?

3 answers

For the most part they are unreactive and don't form many compounds. For years everyone thought they formed NO compounds; however, a few compounds of some of the noble gases are now known to exist.
group 8 elements have full valence electron shells. (valence electron are in the outermost shell of an atom) this makes the elements in group 8 stable or inert. they are also transition metals.
hope this helps!
Thank you
