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.
