Selenium's atomic number is 34 and its symbol is Se. Selenium is a nonmetal that has three common allotropes which are metallic gray, red, or glassy black. It is produced as a byproduct when refining metal sulfide ores. Selenium is most commonly used as a pigment, although you might have also seen it listed as an ingredient in a supplementary vitamin.
