Facts about hassium

Here are a few interesting facts about hassium element.

  1. Peter Armbruster, Gottfried Munzenberg and other team members discovered the hassium element in the year 1984.
  2. Hassium was given its name from the name “Hesse” (which is a state in Germany).
  3. There are around 12 isotopes of hassium and all the isotopes are radioactive in nature.
  4. Hassium is available in very less quantity and it is artificially prepared in the lab.
  5. 270Hs is the isotope of hassium which has the longest half life (which is only 9 seconds).

Properties of hassium

Here is a list of some physical properties and chemical properties of hassium.

  • The half life of hassium is very short and it is a highly radioactive element.
  • It is predicted that hassium is solid at room temperature and pressure.
  • The estimated density of hassium is between 27-29 g/cm3 and its most stable isotope has an atomic mass 277 amu.
  • Hassium has many oxidation states but its most common oxidation state is +8.
