Uses of Hassium

  • Since the element is not found freely in nature, hassium does not find many commercial applications coming in any field. The metal is rarely used in the field of scientific research and applications.
  • Being a radioactive element, it is said to be harmful in some case of studies.

Properties of Hassium

  • Hassium (Hs) with an atomic number 108 is said to be belonging to the group 8 and period 7. It is synthetic in nature, which is produced in minute quantities.
  • The isotopes of this metal have relatively shorter lives of about 22 seconds and have about nine synthetic isotopes with one of its more stable isotope being hassium is 270.
  • Hassium can be produced artificially in small amounts. It is created by bombarding atoms of the isotopes of lead i.e., 208 Pb, with the ions of the iron isotope 58 Fe. The team members of Darmstadt made use of the linear accelerator for the process of bombarding and produced 265 Hs along with a free neutron.
  • This metal was first discovered by team members of Peter Armbruster and Gottfried Münzenber in Germany in the year 1984. Apart from having only one single and stable natural isotope, hassium has about 12 synthetic isotopes having mass numbers between 263 – 277.
