Hassium

Hassium information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.

Hassium's appearance is unknown but it is suspected to be silvery white or metallic grey in color. Little is known about the element and it has no known uses. Hassium is a synthetic element that is not present in the environment.

Hassium Bohr ModelHassium is a is a D-Block, Group 8, Period 7 element. The number of electrons in each of Hassium's shells is 2, 8, 18, 32, 32, 14, 2 and its electronic configuration is [Rn] 5f14 6d6 7s2. In its elemental form Hassium's CAS number is 54037-57-9

Hassium was first created in 1984 by a team headed by Peter Armbruster and Gottfried Münzenber at the Heavy Ion Research Laboratory in Darmstadt, Germany.
