The element is rarest on earth. only 30 g total in earth's crust. No body actually "see" it, because if you collect enough of the stuff, its own isotope radiation will heat up enough to vaporize it. People only can "assume" what its appearance would be... What element is it? (since dave is not here... I assume he is looking for the element somewhere in the wild). No reward for anyone answer correctly... Punishment will be to define Dave's GPS coordinate and get him back on time for next element question... ;-) Happy Friday.
