3 Facts
3.1 Interesting Facts
- Palladium alloys are used for Jewelry contains (95% Palladium and 5% Ruthenium)
- In the late 1800s, Palladium metal used have more economical value than the Platinum metal.
- Palladium element is known as a good catalyst
- Molybdenum is highly reactive metal, hence not found free in nature .
- Till 18th century Molybdenum element were often mistaken as a carbon or Lead.
