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.
  
  • Molybdenum is highly reactive metal, hence not found free in nature .
  • Till 18th century Molybdenum element were often mistaken as a carbon or Lead.
