Molybdenum is a transition metal with an electronegativity of 2.16 on the Pauling scale. It does not visibly react with oxygen or water at room temperature. Weak oxidation of molybdenum starts at 300 °C (572 °F); bulk oxidation occurs at temperatures above 600 °C, resulting in molybdenum trioxide. Meer weergeven Molybdenum is a chemical element with the symbol Mo and atomic number 42 which is located in period 5 and group 6. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, … Meer weergeven Molybdenum forms chemical compounds in oxidation states −IV and from −II to +VI. Higher oxidation states are more relevant to its terrestrial occurrence and its biological roles, mid-level oxidation states are often associated with metal clusters, and very low … Meer weergeven Molybdenum is the 54th most abundant element in the Earth's crust with an average of 1.5 parts per million and the 25th most abundant element in its oceans, with an average of 10 parts per billion; it is the 42nd most abundant element in the Universe. … Meer weergeven Mo-containing enzymes Molybdenum is an essential element in most organisms; a 2008 research paper speculated … Meer weergeven Physical properties In its pure form, molybdenum is a silvery-grey metal with a Mohs hardness of 5.5 and a standard … Meer weergeven Molybdenite—the principal ore from which molybdenum is now extracted—was previously known as molybdena.
