Facts
Interesting Facts
  • Seaborgium most stable isotope is Sg and it has 2.1 min of half- life.
  • And other isotopes of Seaborgium have half-lives as short as 3 ms.
  
  • 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 Seaborgium 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.
