The properties of hassium are only predicted, not experimentally determined:
- density: 40,7 g/cm3
- empirical atomic radius: 134 pm
- first ionization energy: 733,3 kJ/mol
- crystalline structure: hexagonal close packed
- valences: 2, 3, 4, 5, 6, 8

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].
