We elaborate the uses of Molybdenum and atomic properties with characteristics. Molybdenum is a metallic gray chemical element with atomic number 42. Its symbol is Mo and it belongs to the group of transition metals and its normal state in nature is solid. Molybdenum is located at position 42 on the periodic table.
On this page you can discover the chemical properties of molybdenum and information about molybdenum and other elements of the periodic table such as chromium, tungsten (tungsten), niobium or technetium. You will also learn what molybdenum is for and you will know its uses through its properties associated with molybdenum such as its atomic number or the usual state in which molybdenum can be found.
You can see qualities of molybdenum such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in molybdenum atoms and other properties.
For some elements, part of this information is unknown. In these cases we show the properties attributed to them.
The transition metals, also called transition elements, is the group to which molybdenum belongs. In this group of chemical elements to which molybdenum belongs, are those located in the central part of the periodic table, specifically in block d. Among the characteristics that molybdenum has, as well as those of the rest of the transition metals, is to include in its electronic configuration the d orbital, partially filled with electrons. Properties of this type of metal, among which molybdenum is found, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.
The state of molybdenum in its natural form is solid. Molybdenum is a chemical element with a metallic gray appearance and belongs to the group of transition metals. Molybdenum’s atomic number is 42. Molybdenum’s chemical symbol is Mo. Molybdenum’s melting point is 2896 degrees Kelvin, or 2623.85 degrees Celsius, or degrees Centigrade. The boiling point of molybdenum is 4912 degrees Kelvin or 4639.85 degrees Celsius or degrees Centigrade.
Uses of molybdenum
Molybdenum has a very high melting point so it is produced and sold as a gray powder. Many moly articles are formed by compressing the powder at a very high pressure.
Most moly is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity, and resistance to corrosion and wear. These “molybdenum steel” alloys are used in engine parts. Other alloys are used in heating elements, drills, and saw blades.
Molybdenum disulfide is used as a lubricating additive. Other uses for moly include catalysts for the petroleum industry, printed circuit inks, pigments, and electrodes.
Atomic Properties of Molybdenum
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. Regarding the position to find molybdenum within the periodic table of elements, molybdenum is found in group 6 and period 5. Molybdenum has an atomic mass of 95.94 u.
The electron configuration of molybdenum is [Kr] 4d55s1. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. Molybdenum’s mean radius is 145 pm, its atomic radius or Bohr radius is 190 pm, and its covalent radius is 154 pm. Molybdenum has a total of 42 electrons whose distribution is as follows: In the first shell it has 2 electrons, in the second it has 8 electrons, in its third shell it has 18 electrons, in the fourth, 13 electrons and in the fifth shell it has 1 electron.
