hey i'm new to chemistry and noticed there are so many heavy elements we rarely see in commercial uses... why not? Theses things like Berkelium or Mendelevium or all those other weirdos don't have unique properties we can harness for anything? at all!?? Seems strange to me.. can somebody shed some light please? thanks.

many of them are unstable, they have relatively short half-lives

Many of them are also not available in big quantities. They are pretty scarce on earth. And unfortunately we do not have the technology to produce elements (such as Berkelium or Mendelevium) in bulk with out current technology!

yeah, that too

hence the term "rare earth elements"
