Molybdenum is a shiny, silvery metal that is essential for many industrial applications. It is primarily used to strengthen steel and other alloys, making them more durable and resistant to heat. This metal is also important in the production of electrical contacts and filaments, as well as in the chemical industry for catalysts. In nature, molybdenum is found in minerals like molybdenite, which is its main source. It plays a crucial role in biological systems as well, being a vital trace element for some organisms, including certain bacteria and plants. Overall, molybdenum is a versatile element with significant importance in both technology and nature.
