Molybdenum is a chemical element with symbol Mo and atomic number 42.
It belongs to Period 5, Group 6 i.e. the d - block.
It's electronic configuration is [Kr] 4d5 5s1.
Phase at STP : Solid
Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals.
The free element, a silvery metal with a gray cast, has the sixth-highest melting point of any element.
It readily forms hard, stable carbides in alloys, and for this reason most of world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys.
