Selenium is a chemical element found in a wide variety of products.
The primary use of selenium is to decolorize glass. Also used in power surge protectors, laser printers, photocopiers, steels, semiconductors in Photocells, and assorted medicinal preparations. Selenium is also used in Diamond Galaxy Machines, lithium–selenium (Li–Se) battery, Solar Cells.
Here are some interesting facts about selenium:
Selenium gets its name from the Greek word “Selene,” which means “moon.”
Selene was the Greek goddess of the moon.
Selenium has atomic number 34, meaning each atom has 34 protons. The element symbol of selenium is “Se”.
Selenium was discovered jointly in 1817 by Swedish chemists Jöns Jakob Berzelius (1779–1848) and Johan Gottlieb Gahn (1745–1818).
Although it is uncommonly found, selenium does exist in relatively pure form, free in nature.
Selenium is a nonmetal. Like many nonmetals, it exhibits different colors and structures.
Selenium is essential for proper nutrition in many organisms, including humans. But is toxic in larger amounts.
Brazil nuts are high in selenium, even if they are grown in soil that is not rich in the element. A single nut provides enough selenium to meet the daily requirement for a human adult.
English electrical engineer Willoughby Smith (1828–1891) discovered that selenium reacts to light (photoelectric effect), leading to its use as a light sensor in the 1870s. Scottish-born American inventor Alexander Graham Bell (1847–1922) made a selenium-based photo-phone in 1879.
There are six natural isotopes of selenium. One is radioactive, while other five are stable.
Selenium salts are used to help control dandruff.
Selenium is protective against mercury poisoning.
Some plants require high levels of selenium to survive, so the presence of those plants means the soil is rich with the element.
Selenium and its compounds are anti-fungal. Liquid selenium exhibits extremely high surface tension. Approximately 2,000 tons of selenium are extracted annually worldwide.
Selenium is most commonly produced as a byproduct of copper refining. The element was featured in the films “Ghost busters” and “Evolution.”
Granules of Selenium in 3N, 4N, 5N, 6N is available with us.
