Facts
Interesting Facts
Meitnerium is named after Lise Meitner, an Austrian physicist.  
  • At room temperature mercury is found in a liquid state.
  • A coin of pound or rupees floats in mercury.
  • Because of its low melting point and boiling point it is used in thermometers.

Uses
Uses & Benefits
  • Currently known uses of Meitnerium metal are limited to research purpose only.
  
  • 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.
