Hassium is a radio active atom that was obtained by nuclear fusion techniques. It does not occur in nature.

The International Union of Pure and Applied Chemistry (IUPAC) had given the new element the name Unniloctium, with the symbol Uno. In 1997 the IUPAC accepted the name hassium.

Who made hassium?: Gottfried Münzenberg, Peter Armbruster and their team at the Institute for Heavy Ion Research in Darmstadt, Germany in 1984.

About hassium: Hassium was made by bombarding lead atoms with iron atoms at the Heavy Ion Research Institute. Only a few atoms of hassium have ever been made. Hassium atoms have a half life of 22 seconds.
