Hassium Properties

Hassium is a chemical element with the symbol Hs and the atomic number 108. It is not known to occur in nature and has been made only in laboratories in minuscule quantities. Hassium is highly radioactive; the most stable known isotope, 269Hs, has a half-life of approximately 16 seconds.  It was synthesized and identified in 1984 by West German researchers at the Institute for Heavy Ion Research in Darmstadt. On the basis of its position in the periodic table of the elements, it is expected to have chemical properties similar to those of osmium.

Hassium Element Properties

Characteristics of Hassium

  • In the periodic table of the elements, hassium is a transactinide element, a member of the 7th period and group 8. It is thus the sixth member of the 6d series of transition metals.
  • 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.
