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.
  
  • Osmium metal does not oxidize in air unless it is heated.
  • But if it heated den it forms Osmium Tetroxide, which is highly toxic.
