Facts

Interesting Facts
  • Heat capacity of Lithium is very high.
  • Lithium inflammable and highly explosive metal, hence it has to be stored properly.
  
  • Molybdenum is highly reactive metal, hence not found free in nature .
  • Till 18th century Molybdenum element were often mistaken as a carbon or Lead.
