Hassium

Hassium General

Name:Hassium Symbol:Hs
Type:Transition Metal Atomic weight:265
Density @ 293 K: g/cm3 Atomic volume:cm3/mol
Discovered:

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 with iron nuclei to produce three atoms of hassium. The name hassium is derived from the Latin name for the German state of Hesse.
