what are the physical properties of the above-mentioned element?
It should crystallize in the hexagonal close-packed structure.
Hassium
 Hassium should crystallize in the hexagonal close-packed structure (/ = 1.59), similarly to its lighter congener osmium. Pure metallic hassium is calculated to have a bulk modulus (resistance to uniform compression) of 450 GPa, comparable with that of diamond, 442 GPa. Hassium is expected to have a bulk density of 41 g/cm at standard pressure and temperature, the highest of any of the 118 known elements and nearly twice the highest density of an element observed to this day (22.6 g/cm).
what is hassium? It is a chemical element. where is it naturally found? It is not known to occur naturally on Earth. is it used in any fusion reactions? Yes, it was used in Cold fusion. where does the name of the element come from? Under Mendeleev's nomenclature, It would be known as "eka-osmium", as in "the first element below osmium in the periodic table".

Hassium [SEP] Physical and atomic
The atomic radius of hassium is expected to be around 126 pm. Due to the relativistic stabilization of the 7s orbital and destabilization of the 6d orbital, the Hs ion is predicted to have an electron configuration of [Rn] 5f 6d 7s, giving up a 6d electron instead of a 7s electron, which is the opposite of the behaviour of its lighter homologues. The Hs ion is expected to have an electron configuration of [Rn] 5f 6d 7s, analogous to that calculated for the Os ion. In chemical compounds, hassium is calculated to display bonding characteristic for a d-block element, whose bonding will be primarily executed by 6d and 6d orbitals; compared to the elements from the previous periods, 7s, 6p, 6p, and 7p orbitals should be more important.
