Facts

Interesting Facts
  • Molybdenum is highly reactive metal, hence not found free in nature .
  • Till 18th century Molybdenum element were often mistaken as a carbon or Lead.
  
  • Rutherfordium does not occur in nature as it is a synthetic element.
  • Till date Rutherfordium metal has 15 radioisotopes created synthetically.
