Facts
Interesting Facts
  • Heat capacity of Lithium is very high.
  • Lithium inflammable and highly explosive metal, hence it has to be stored properly.
  
  • Radium metal is the heaviest metal of Alkaline earth metals column.
  • Radium metal is highly radioactive and does not have any stable isotopes.
