Suspecting that hassium has properties similar to osmium and other so-called group 8 elements, chemists placed hassium on the periodic table directly below osmium.
The team recently built and installed an instrument at the UNILAC heavy-ion accelerator in Darmstadt, Germany, that can detect and analyze hassium. When the researchers slammed atoms of the artificial isotope curium-248 with magnesium-26 atoms, they ended up with at least six molecules of hassium.
