Selenium is a chemical element with the atomic number 34 and the symbol Se, classified as a nonmetal in group 16 of the periodic table, known as the chalcogens. It exists in several allotropic forms, including gray metallic, red crystalline, and amorphous red powder, with the gray form being the most stable under standard conditions.

Chemically similar to sulfur and tellurium, selenium has an atomic mass of 78.96 and plays essential roles in biological systems at trace levels while being toxic at higher concentrations.

Selenium’s applications span electronics, where it is used in photovoltaic cells, rectifiers, and photocopiers due to its photoconductive qualities; the glass industry, for decolorizing and imparting red hues; and alloys, rubber vulcanization, and pigments. In agriculture, sodium selenite supplements animal feeds to prevent deficiency-related diseases.

Biologically, selenium is an essential trace element incorporated into selenoproteins, which function as antioxidants, support thyroid hormone metabolism, DNA synthesis, reproduction, and immune response.
