History

History

The element Hafnium was discovered by Dirk Coster in year 1923 in Denmark. Hafnium derived its name from from Hafnia, the New Latin name for Copenhagen

The element Hassium was discovered by Gesellschaft für Schwerionenforschung in year 1984 in Germany. Hassium derived its name derived its name from from Hesse, Germany, where the element was first synthesized
