3 Facts
3.1 Interesting Facts
- Tungsten element has the second highest melting point.
- Pure tungsten can easily cut down with the help of hacksaw.
- Molybdenum is highly reactive metal, hence not found free in nature .
- Till 18th century Molybdenum element were often mistaken as a carbon or Lead.
