Hassium elements are classified as transition metals. It was discovered by a team led by Peter Armbruster and Gottfried Münzenber in 1984.

Hassium was developed in 1984 by Pion Armbruster and Gottfried Münzenber at the Heavy Ion Research Center in Darmstadt, Germany.

Source: Hassim is a synthetic radioactive metal produced by nuclear bombing. Only a trace amount is produced. Bombard 208 Pb with 58 Pe to manufacture Hashium

Isotope: Hassium has 12 isotopes with known half-life and mass numbers from 263 to 277. It is not stable. The most stable isotope is 269 H with a half-life of 7 s.

According to the naming of Mendeleev's unnamed, undiscovered elements, Hassium should be called Eka Osmium. In 1979, IUPAC published several recommendations based on its elements called unniloctium (corresponding Uno symbol). Determine the system element name, the element is discovered (and discovered and confirmed). Chemistry classes and advanced textbooks are widely used in the chemical industry, but these recommendations are largely ignored by scientists in this field, and "Element 108", the symbols E 108, (108), or simply 108 It is called, or use the recommendations. Name "Hashium"

Hashium is a synthetic chemical element with the symbol Hs and atomic number 108. It was named after the Hessian state in Germany. It is a synthetic element and radioactive; the most stable and known isotope 270 H has a half-life of about 10 seconds. To date, over 100 atoms of hash have been synthesized. In the periodic table of elements, it is a transimine element in the d region. Hassim is a member of No. 7 and belongs to the eighth element: hence it is the sixth member of the transition metal 6 d series. Chemical experiments have confirmed that hashium appears as a heavier homologue of ruthenium in group 8. The chemical nature of hashium is characterized only in part, but its chemical properties are equivalent to those of the other eight elements. Many of them are expected to be silver metal where Hassium readily reacts with oxygen in the air to form volatile tetraoxide.

Hashium (Hs), an artificial production factor belonging to Uranium Group, has atomic number 108. According to its position in the periodic table it is expected to have the same chemical properties as ruthenium. The GSI team led by Peter Armbruster generated a Hassium isotope in nuclear fusion reaction by irradiating lead 208 with iron ions 58. The isotopic mass is 265, very unstable, with a half-life of only 2 ms. Experiments conducted by A. G. Demin and other researchers at the Russian Federation Atomic Energy Research Institute in Dubna showed that there are two Hassium isotopes, masses 263 and 264.
