Well Thankfully Hassium (106)and it’s anti matter form Hassnotium is safe. Well other than being wildly radioactive with an extremely short half life. When Chemistry meets Physics, lots of funny things happen. Sorry if I quark myself up.
Bohrium is boring.
In the early '40s all the plutonium in the world was stored in a cigar box on Glenn Seaborg's desk at Berkeley.
Hassnotium can decay into either Hasslessium or Hassmorium.
The most elusive of the transfermium elements (the group with atomic numbers > 100) is Unobtanium (Unob), atomic number ~ 119. Highly prized by Steampunkers.
