2 Facts

2.1 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.
