Selenium is a chemical element with symbol Se and atomic number 34. Classified as a nonmetal, Selenium is a solid at room temperature.
What is Se in mineral?
Selenium (Se) is an essential trace mineral occurring naturally in the soil.
Is se a metalloid?
Six elements are commonly recognized as metalloids; arsenic (As), antimony (Sb), boron (B), germanium (Ge), silicon (Si) and tellurium (Te). Certain other elements, like selenium (Se), are sometimes added to the list. The natural abundance of metalloids in the environment varies greatly.

Is Se an anion?
A selenide is a chemical compound containing a selenium anion with oxidation number of −2 (Se2−), much as sulfur does in a sulfide. The chemistry of the selenides and sulfides is similar. Similar to sulfide, in aqueous solution, the selenide ion, Se2−, is prevalent only in very basic conditions.

What is selenium good for?
Selenium plays an important role in the health of your immune system. This antioxidant helps lower oxidative stress in your body, which reduces inflammation and enhances immunity. Studies have demonstrated that increased blood levels of selenium are associated with enhanced immune response.
Is se metalloid or non metal?
The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids. When elements combine to form compounds, there are two major types of bonding that can result….Metals, Metalloids, and Nonmetals.
