Word origin

The word 'selenium' comes from the Greek word 'selฤ“nฤ“', meaning 'moon', due to its discovery during the study of tellurium, which was named after the Latin word for 'earth'. Selenium was discovered in 1817 by the Swedish chemist Jรถns Jacob Berzelius and his assistant Johan Gottlieb Gahn while trying to isolate tellurium from a substance that had a similar appearance. Its chemical properties were fully studied by the chemist Dmitri Mendeleev in the late 19th century, where it was classified in the periodic table. Over time, selenium has been recognized not only for its role in industrial applications but also for its essential function in biological systems, particularly as an antioxidant and in the enzyme glutathione peroxidase. Its use in technology, especially in photography and electronics, has grown since the mid-20th century, establishing selenium as both a vital nutrient and a key material in various technological applications.
