On this page you can discover the chemical properties of selenium and information about selenium and other elements on the periodic table such as sulfur, tellurium, arsenic or bromine. You will also learn what selenium is for and you will know what its uses are through its properties associated with selenium such as its atomic number or the usual state in which selenium can be found.

You can see qualities of selenium 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 selenium 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 selenium

One of the properties of non-metal elements like selenium is for example that non-metal elements are poor conductors of heat and electricity. Selenium, like the other non-metal elements, has no luster. Due to their brittleness, nonmetals like selenium cannot be flattened to form sheets or stretched to become threads.

The state of selenium in its natural form is solid. Selenium is a metallic gray-looking chemical element and belongs to the group of nonmetals. The atomic number of selenium is 34. The chemical symbol for selenium is Se. The melting point of selenium is 494 degrees Kelvin or 221.85 degrees Celsius or degrees Celsius. The boiling point of selenium is 957.8 degrees Kelvin or 685.65 degrees Celsius or degrees Celsius.

Uses of selenium

Selenium is considered to be a nonmetal. Selenium is normally produced during the refining of copper or the creation of sulfuric acid. Although it is toxic in large doses, it is an essential micronutrient in the body. It has many other applications in different industries. If you have ever wondered what selenium is for , here is a list of its possible uses:

• The most common use of selenium is in the production of glass. Due to the fact that selenium causes a red color in the glass, it can also be used to tint the glass red. It can also be used to nullify green or yellow tints caused by other impurities during the glass manufacturing process.
• Small amounts of selenium compounds are used in rubber manufacturing.
• Selenium can be mixed with another chemical element called bismuth to create a lead- free brass .
• Selenium Sulfide is a common ingredient in anti-dandruff shampoo that kills the fungus that causes scaling of the scalp. It can also be used to treat certain skin problems caused by other fungi.
• Long ago, selenium was widely used in electronics, but its use for this purpose has been reduced in recent years. It is still used in solar cells, photocopiers, and light meters. It is also used in blue and white LEDs.
• Selenium is used in some x-ray cameras. Also used for black and white photography.

Atomic properties of selenium

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. As for the position where to find selenium within the periodic table of the elements, selenium is in group 16 and period 4. Selenium has an atomic mass of 78.96 u.

The electronic configuration of selenium is [Ar] 3d104p44s2. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The median radius of selenium is 115 pm, its atomic radius or Bohr radius is 103 pm, its covalent radius is 116 pm, and its Van der Waals radius is 190 pm. Selenium has a total of 34 electrons whose distribution is as follows: In the first layer it has 2 electrons, in the second it has 8 electrons, in its third layer it has 18 electrons and in the fourth one, 6 electrons.
