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 Sodium metal is very soft as it can be chopped down into pieces with butter knife.
- The most common compound of Sodium is NaCl (Salt).
