History
History |
The element Darmstadtium was discovered by Gesellschaft für Schwerionenforschung in year 1994 in Germany. Darmstadtium derived its name from from Darmstadt, Germany, where the element was first synthesized |
The element Rubidium was discovered by Robert Bunsen in year 1861 in Germany. Rubidium derived its name derived its name from from the Latin rubidus, meaning 'deep red' |
