Beryllium is a chemical element with symbol Be and atomic number 4. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars beryllium is depleted as it is fused and creates larger elements.
Beryllium and its compounds can produce dermatitis, conjunctivities, and other contact effects; however, these manifestations are rare. There is some evidence that beryllium in soils is toxic to plant life; no evidence was found on the effects of atmospheric beryllium on plants or on materials.
Beryllium is used industrially in three forms: as a pure metal, as beryllium oxide, and most commonly, as an alloy with copper, aluminum, magnesium, or nickel. Beryllium oxide (called beryllia) is known for its high heat capacity and is an important component of certain sensitive electronic equipment.
