Atomic weight can be defined as the total weight or mass of an atom. Atomic mass and weight are relative terms. Let us find the atomic weight of Hassium.

The atomic weight or atomic mass of Hassium is 269 u.

Hassium atomic Density

Atomic density is the atomic characteristics, which denotes the number of atoms, exist in per cm³. Let us discuss the atomic density of Hs here.

The atomic density of Hassium is 27–29 g/cm³. 

Hassium Van der Waals radius

Van der Waals radius is the imaginary representation of closest distance of the hard sphere of Hassium from another atom. Let us identify this radius of Hassium.  

Van der Waals radius of Hassium is 200pm.

Hassium isotopes

Isotopes refer to the atoms of one specific element, which are just different from each other by the number of neutrons. Let us identify the number of isotopes of Hassium here.

Hassium has almost 12 known isotopes from ²⁶³Hs to ²⁷⁷Hs. ²⁷⁷Hs is the most stable isotope of Hassium. 

Hassium electronic shell

Electron shell refers to the shell in which the atoms keep their electrons. These are the pathway of electrons around the nucleons. Let us find the number of electron shell in Hs.

One Hassium atom has total of 7 electronic shells. The number of electrons in the shells are 2, 8, 18, 32, 32, 14, and 2.

Hassium energy of first ionisation

First ionisation energy is the uppermost energy level of atoms which eliminates one electron. Let us find the first ionisation energy of Hs.

The first ionisation energy of Hassium is 730 kJ/mol.

Hassium energy of second ionisation

Second ionisation energy refers to the amount of energy required to reduce the second last valence electron from electronic shell. Second I.E. for Hs is given below.

The second ionisation energy of Hassium is 1760 kJ/mol.

Hassium energy of third ionisation

Third ionisation energy of elements is required to leave the third last electron from the valence shell. Let us look at the third ionization energy of Hassium.

The amount of third ionisation energy of Hassium is 2830 kJ/mol.

Hassium oxidation states

Oxidation states denote the number of electrons that can be lost by the atoms of a specific element. The oxidation numbers or states of Hs are given below.

The most stable oxidation state of Hassium is +8. Other predicted oxidation states are +2, +3, +4 and +6.

Hassium electron configurations

Electronic configuration of periodic element is representation of electronic arrangement in the orbitals of an atom. Let us find this chemical fact for Hassium below.

The electronic configuration of Hassium is [Rn] 5f¹⁴6d⁶7s². Redon is the respective noble gas exists in the same period of Hassium in the table. The mentioned electronic configuration is presented by applying Aufbau principle.

Hassium CAS number

CAS number of Hassium is used as a code for accessing data and information about the element. Let us find the CAS number of Hassium below.

The CAS Identity number of Hassium is 54037-57-9.

Hassium chemical classification

Chemical classification of elements finds uniqueness among the elements, which differs them from other elements in the periodic table. Let us chemically classify Hassium below.

Hassium is highly radioactive element and very unstable one. The most stable isotope of Hassium has been found to possess half-life of 10 second.

Hassium state at room temperature

Periodic elements exist in three different state those are solid, liquid and gaseous. This section will identify the state of Hassium at room temperature.

Hassium is found as a solid element at room temperature.

Is Hassium paramagnetic?

Paramagnetic element has a tendency to being weakly magnetised in presence of magnetic field in the direction of that field. Let us find if Hassium has such tendency or not.

Hassium is not a paramagnetic element. It can be noticed that the last orbital of Hassium atom is filled with paired electrons, which does not satisfy the criteria of being paramagnetic.

Conclusion

Hassium has been identified as one of the most radioactive d-block element in the periodic table. As it has d orbital, it is placed at d-block. The isotopes of Hassium do not have length half-0liofe. The highest half-life of one of the isotopes of Hassium is 1.1 minute. These factors distinguish the element from other periodic elements.
