Discovery of Hassium
Hassium was first made by a team led by Peter Armbruster and Gottfried Münzenber at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1984.
They bombarded lead-208 with iron-58 nuclei to produce three atoms of hassium.
The name hassium is derived from the Latin name for the German state of Hesse.
Appearance and Characteristics
Harmful effects:
Hassium is harmful due to its radioactivity.
Characteristics:
Hassium is a synthetic, radioactive metal and has only been produced in tiny amounts.
Uses of Hassium
Hassium is of research interest only.
Abundance and Isotopes
Abundance earth’s crust: nil
Abundance solar system: parts per billion by weight, parts per trillion by moles
Cost, pure: $ per 100g
Cost, bulk: $ per 100g
Source: Hassium is a synthetic, radioactive metal, created via nuclear bombardment. It has only been produced in minute amounts. Hassium is produced by bombarding 208Pb with 58Fe.
Isotopes: Hassium has 12 isotopes whose half-lives are known, with mass numbers from 263 to 277. None are stable. The most stable isotope is 269Hs, with a half-life of 9.7 seconds.
