A Beginner’s Guide to Understanding Molybdenum’s Chemical Properties
What is Molybdenum?
Molybdenum is a chemical element with the symbol Mo and atomic number 42. This transition metal is known for its high melting point and impressive durability. Found in nature primarily in mineral forms such as molybdenite (MoS₂), it plays a crucial role in various industrial applications.
- Atomic Weight: 95.94 u Melting Point: 2,623°C (4,753°F) Boiling Point: 4,639°C (8,363°F)
Molybdenum was discovered in 1778 by Swedish chemist Carl Wilhelm Scheele and later isolated by Peter Jacob Hjelm in 1781. The name "molybdenum" derives from the Greek word "molybdos," meaning lead, due to its resemblance to lead ores.
