EDIT: No, wait, silly me. :tai: No element with atomic number 115 occurs naturaly. But it will be synthesized some day and will have nothing in particular, except for being extremely unstable just like all those heavy elements. No element with an atomic weight of 115 g/mol would be special though, they are found on Earth. And this time I mean it.

Well element 115 was created inlabs not too long ago but it has life time measured in seconds.

These superheavy elements dont exist naturally on earth or any place in the Universe from what we can tell.
Some physicist have predicted a "Island of Stability" in the superheavy element in which when they reach a certain number they would be stable and have a life time in years instead of seconds. I think it was thought to be in the 115-117 range
Thats pretty much what Lazar was talking about a stable superheavy element.
