The +8 oxidation state is notable for being the highest attained by any chemical element aside from iridium's +9 and is encountered only in xenon, ruthenium, hassium, and iridium.WikiMatrix WikiMatrix
Representing the Periodic Table in Different Ways a site curated by the Michigan State University Alumni Association Knowledge Network Robert Harrison's modern spiral periodic table Janet's Left Step Periodic Table Correction to Physicist periodic table offered by Jeries Rihani as Meitnerium occupies the position that Hassium should have.WikiMatrix WikiMatrix
Hassium-270 evidently forms part of an island of stability, and may even be double magic.WikiMatrix WikiMatrix
Calculations on its ionization potentials, atomic radius, as well as radii, orbital energies, and ground levels of its ionized states are similar to that of osmium, implying that hassium's properties would resemble those of the other group 8 elements, iron, ruthenium, and osmium.WikiMatrix WikiMatrix
In December 2006, hassium-270, with 108 protons and 162 neutrons, was discovered by an international team of scientists led by the Technical University of Munich having the half-life of 22 seconds.WikiMatrix WikiMatrix
108 is the atomic number of hassium.WikiMatrix WikiMatrix
Hassium-270 is now believed to be a doubly magic deformed nucleus, with deformed magic numbers "Z" = 108 and "N" = 162.scb_mt_enth_2020 scb_mt_enth_2020
Chemists have “a new building block in their construction set: hassium, a heavy metal,” reports the German newspaper Süddeutsche Zeitung.jw2019 jw2019
However, between 2001 and 2005, the GSI team studied the reaction 248Cm(26Mg,5n)269Hs, and were able to confirm the decay data for hassium-269 and rutherfordium-261.WikiMatrix WikiMatrix
Hassium is a synthetic chemical element with symbol Hs and atomic number 108.LASER-wikipedia2 LASER-wikipedia2
Chemical series information for elements past hassium (except copernicium), is hypothetical and based on periodic trends.WikiMatrix WikiMatrix
It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs).WikiMatrix WikiMatrix
Both hassium and its new compound are radioactive, unstable, and short-lived and hence are of no immediate practical value.jw2019 jw2019
The group 8 elements show a very distinctive oxide chemistry which allows extrapolations to be made easily for hassium.WikiMatrix WikiMatrix

Hassium is not known to occur naturally on Earth; the half-lives of all its known isotopes are short enough that no primordial hassium would have survived to the present day.WikiMatrix WikiMatrix
Thus hassium is expected to form a stable +8 state.WikiMatrix WikiMatrix

Various calculations show that hassium should be the heaviest known group 8 element, consistent with the periodic law.WikiMatrix WikiMatrix
Although all elements up to oganesson have been discovered, of the elements above hassium (element 108), only copernicium (element 112), nihonium (element 113), and flerovium (element 114) have known chemical properties, and only for copernicium is there enough evidence for a conclusive categorisation at present.WikiMatrix WikiMatrix
