Not known
Impossible to answer, but very probable no smell.
It is considered that hassium has chemical properties similar than osmium, being his homologue.Two compounds of hassium are known: HsO4 and Na2[HsO4(OH)2].
Hassium, previously known as unniloctium, with the chemical symbol Hs (previously Uno) has the atomic number 108.
Only two compounds of hassium are known today: HsO4 and Na2[HsO4(OH)2].
Now are known only two hassium compounds: HsO4 and Na2[HsO4(OH)2].
As a radioactive element, yes.
