Livermorium - the smelliest element

The element Livermorium (element 116, named after Lawrence Livermore National Laboratory) was created in 2000. It's in the same column of the periodic table as sulfur and it is speculated that it might be the smelliest of all elements, but since it has a half life of "tens of milliseconds," no one has been able to make the hydrogen compound of it and given it a proper sniff. Also, it's radioactive.
