Darmstadtium
Darmstadtium General
| Name:Darmstadtium | Symbol:Ds |
| Type:Transition Metal | Atomic weight:281 |
| Density @ 293 K:g/cm3 | Atomic volume: cm3/mol |
|
Discovered:
Darmstadtium was first synthesized by research scientists at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1994. The element was made by fusing nickel atoms and lead atoms in a heavy ion accelerator. Four atoms of Darmstadtium were produced in the first experiment. The element is named after the city where it was first made. |
