You will also learn what manganese is for and learn about its uses through its properties associated with manganese, such as its atomic number or the usual state in which manganese can be found.
You can see manganese qualities 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 manganese atoms and other properties.
For some elements some of this information is unknown. In these cases we show the properties attributed to them.
Properties of manganese
Transition metals, also called transition elements is the group to which manganese belongs. In this group of chemical elements to which manganese belongs, there are those located in the central part of the periodic table, specifically in block d. Among the characteristics that manganese has, as well as those of other tansition metals, is that of including in its electronic configuration the d orbital, partially full of electrons. Properties of this type of metal, among which manganese is found, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat.
The state of manganese in its natural form is solid (generally non-magnetic). Manganese is a metallic silver-looking chemical element and belongs to the group of transition metals. The atomic number for manganese is 25. The chemical symbol for manganese is Mn. The melting point of manganese is 1517 degrees Kelvin or -272.15 degrees Celsius or degrees Celsius. The boiling point of manganese is 2235 degrees Kelvin or 1962.85 degrees Celsius or degrees Celsius.
Uses of manganese
Manganese is a very important metal that is used in a wide variety of different applications. If you’ve ever wondered what manganese is for , here is a list of its possible uses:
- The traquetreo engines are reduced by the use of a manganese compound is added to gasoline without lead . This increases the octane number of the fuel.
- Manganese is used in standard disposable batteries.
- Manganese is essential for producing steel and iron . Manganese is an essential component for the manufacture of low-cost stainless steel.
- Manganese is alloyed with aluminum to produce a metal that is more resistant to corrosion. Most aluminum beverage cans contain between 0.8% and 1.5% manganese.
- In chemistry, manganese oxide is used to oxidize benzyl alcohol.
- Iron contamination can cause glass to tint green. Since ancient times, a manganese compound has been added to the glass to counteract this effect.
- The oxygen and chlorine are processed using manganese dioxide. This same compound is also a brown pigment that can be used to make paint.
- Glass and ceramics can be colored using various manganese compounds.
- In some parts of the world, manganese is used to make coins.
Atomic properties of manganese
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.
