Molybdenum

metals · chemistry · rare elements

Super strong and tough. Molybdenum is a metal that stays strong even at very high temperatures, which is why factories use it in tools, airplane parts, and machinery that gets incredibly hot.

Mistaken for lead. The name molybdenum comes from an Ancient Greek word meaning lead, because the rocks containing molybdenum ore looked so similar to lead ore that people confused them for thousands of years.

Found in 1778. A Swedish scientist named Carl Wilhelm Scheele discovered molybdenum in 1778, and then another scientist named Peter Jacob Hjelm figured out how to isolate the pure metal in 1781.

Makes alloys better. When molybdenum is mixed with other metals like steel, it makes them harder and more flexible, which is why it's used in things like drill bits and car parts that need to be really durable.
