What is Mo? The important knowledge about Mo

  1. Definition of Mo
    Mo, also known as Molybdenum, is a chemical element with the symbol Mo and an atomic number of 42. It is in group 6, period 5 of the periodic table. Molybdenum is a silvery-gray metal that is very hard and has good electrical and thermal conductivity. It has an average atomic mass of 95.96 u, its molecular structure is Mo₈, and a common ion of it is Mo³⁺.

  2. Properties of Mo
    Mo is solid at room temperature. Most commonly, it is a silvery-gray metal, has no characteristic odor and its PH level cannot be measured because it is insoluble in water. It does not react with dilute acids but dissolves in concentrated acids.

  3. Common Chemical Reactions of Mo
    Mo does not react with metals or non-metals but can form various salts. For example, when Mo reacts with concentrated acid, it forms molybdenum trioxide and hydrochloric acid.

  4. Preparation of Mo
    Mo is usually obtained from molybdenite ore. This process involves several steps such as crushing the ore, separating molybdenum from the impurities, and then converting it into molybdenum trioxide through oxidation. Finally, molybdenum trioxide is reduced with hydrogen to create metallic molybdenum.
