The word "Molybdena" is spelled as [muh-lib-dee-nuh], with the stress on the second syllable. It is the outdated name for molybdenum trioxide, a metallic element that is commonly used in the production of steel and other alloys. The spelling of "Molybdena" is derived from the Latin word "molybdaena," which means "lead-like." The word was used to identify the mineral form of molybdenum trioxide, which was commonly found in lead ores.
Molybdena is a noun that refers to a metallic element known as molybdenum, denoted by the symbol Mo in the periodic table. It is a silvery-white transition metal that belongs to Group 6, Period 5 of the periodic table. Molybdena has an atomic number of 42 and an atomic weight of approximately 95.95.
The term "molybdena" is often used interchangeably with molybdenum, although it specifically denotes the element in its natural form found in mineral deposits. Molybdena is a relatively rare element and is primarily obtained from molybdenite, a sulfide mineral. It also occurs in small quantities in various other minerals and as a trace element in certain rocks.
Molybdena possesses attractive physical and chemical properties, making it a valuable element in various industrial applications. It has a high melting point, excellent electrical conductivity, and is highly resistant to corrosion and erosion. These characteristics make molybdena ideal for use in alloys, particularly in the production of high-strength steels, stainless steels, and superalloys. Additionally, molybdena finds use as a catalyst in numerous chemical reactions, as a lubricant additive, and in electronics due to its ability to form stable oxide layers.
In conclusion, molybdena is the common term used to refer to the metallic element molybdenum, which exhibits remarkable properties suitable for diverse applications in various industries.
An ore found in various rocks, and in veins with tin and other ores, closely resembling in colour that of fresh-cut metallic lead.

The word molybdena is derived from the Ancient Greek word molybdaina. It was a term used to refer to a type of lead ore that contained the element molybdenum. The Greek word molybdaina itself is believed to have originated from the Persian word molybdos, which means lead ore or dark stone.
