Hassium like many larger atoms has only been created in the laboratory and does not exist in nature. Hassium has a half life of approximately 16 seconds hence why very little is known about it. The first attempt to create Hassium was made at the Joint Institute for Nuclear Research in Dubna in 1978 but it was unsuccessful. It was not until 1984 that German team of scientists succeeded in synthesising Hassium. Hassium is named after the German state of Hesse. Experiments have been conducted to determine the properties of Hassium, acting as a heavier osmium. As so little of it has been created the melting and boiling point have not been analysed.
