Uses & Benefits
- It is a liquid metal at room temperature, but it is a toxic heavy metal and hence many uses of mercury are under review or phased out.
- It is manly used as a catalysts in chemical industry.
  
- Currently known uses of Darmstadtium metal are limited to research purpose only. As only few atoms of this metal are produced.
