Molybdenum is highly reactive metal, hence not found free in nature .
Till 18th century Molybdenum element were often mistaken as a carbon or Lead.

Found in Minerals, Mining, Ores of Minerals

Its alloys are used to make engine parts, drills, saw blade, etc.

Lubricant additive made up of Molybdenum disulfide is commonly used in the industry. It is also used as a catalyst.

Naturally occurring minor elements include Cadmium.

Cadmium is released into atmosphere to control volcanic eruption and forest fires.

It is used for electroplating of Steel for corrosion resistance.

It can absorb neutrons and used in nuclear reactor to control atomic fission.

Found As a By-product, Found in Minerals, Mining

Karl Samuel Leberecht Hermann and Friedrich Stromeyer

In 1817

It has very limited uses as it is a toxic metal and it can cause birth defects, cancer, etc.
Almost 80% of Cadmium metal is used in Nickel cadmium Batteries and now it is getting replaced with nickel hydride.
