    Selenium is a chemical element from the group of chalcohols. Selenium, metallic and non-metallic modifications may exist. Gray metallic selenium is considered the most stable modification. It has semi-metallic properties. The red selenium is non-metallic and passes above 80°C into the gray metallic selenium. Third modification is black selenium. This converts above 80°C to gray metallic modification. In addition, selenium metal has six naturally occurring isotopes. Five of them are stable.

    Selenium has a great economic meaning and is essential for all forms of life. In medicine, selenium based preparations are used to treat skin diseases.
