What Is Selenium

Selenium (Se) is a chemical nonmetal element with an atomic mass of 78.96 and atomic number of 34. It is groups with chalcogens or chalk-formers. It is reactive enough such that one cannot find it in nature in its elemental state. But, instead, it may be acquired as a by-product from other materials after refining. Sulfide ores like pyrites are good sources of selenium.

Commercially, selenium is used as a raw material for pigments and for glassmaking. In electronics, this element is combined with silicon to make semiconductors.

As you may have known, selenium is an essential part of our bodies’ nutrition. This suggests that we should maintain a good level of this trace mineral.
