About Selenium 78 Isotope

Selenium 78 Metal (Selenium-78) is a stable (non-radioactive) isotope of Selenium. It is both naturally occurring and produced by fission. Selenium 78 Metal is one of over 250 stable metallic isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications. Selenium Metal 78 additionally has special application in bioavailability as an essential nutrient. Selenium Metal is also available in ultra high purity and as nanoparticles. For thin film applications it is available as rod, pellets, pieces, granules and sputtering targets and as either an ingot or powder. Selenium Metal 78 isotopic material is generally immediately available. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Selenium Bohr ModelSee more Selenium products. Selenium (atomic symbol: Se, atomic number: 34) is a Block P, Group 16, Period 4 element with an atomic radius of 78.96. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d10 4s2 4p4. The selenium atom has a radius of 120 pm and a Van der Waals radius of 190 pm. Selenium is a non-metal with several allotropes: a black, vitreous form with an irregular crystal structure three red-colored forms with monoclinic crystal structures and a gray form with a hexagonal crystal structure, the most stable and dense form of the element. Elemental SeleniumOne of the mose common uses for selenium is in glass production the red tint that it lends to glass neutralizes green or yellow tints from impurities in the glass materials. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin of the name Selenium comes from the Greek word "Selênê," meaning moon.
