Introduction
From the Latin Hassia meaning Germany. Discovered in 1984 by a team of physicist led German physicist Peter Armbruster & Gottfried Muzenberg at the Gesellshaft fur Schwerionenforschung.
Occurrence
- hassium-265 produced by fusion of lead-208 with iron-58
- about 40 atoms of hassium-265 have been identified
- hassium-267 was produces by fusion of sulfur-34 with uranium-238
- hassium-269 & hassium-270 were produced by fusion of magnesium-26 with curium-248
Characteristics
- by periodic table, suggested to be member of group 8 & therefore similar to its lighter homologs ruthenium [Ru] & osmium [Os] which form highly volatile tetroxides
- highly radioactive
- 6 isotopes of hassium, 264-267, 269 & 270
- all isotopes emit alpha-particles
- 1/2life ranges from 0.5 millisecond for hassium-264 to 21 seconds form hassium-270
- hassium transmutes to known isotopes of seaborgium, rutherfordium, nobelium & fermium
Uses
