Arsenide IonErbium Arsenide is a crystalline solid used as a semiconductor and in photo optic applications.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.

Erbium(Er) atomic and molecular weight, atomic number and elemental symbolErbium is a Block F, Group 3, Period 6 element. The number of electrons in each of Erbium's shells is 2, 8, 18, 30, 8, 2 and its electronic configuration is [Xe]4f12 6s2. In its elemental form erbium's CAS number is 7440-52-0. The erbium atom has a radius of 173.4.pm and it's Van der Waals radius is unknown. Erbium is moderately toxic. Erbium has application in glass coloring, as an amplifier in fiber optics, and in lasers for medical and dental use.Erbium Bohr Model Erbium is Elemental Erbiumavailable as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. The ion has a very narrow absorption band coloring erbium salts pink. It is therefore used in eyeware and decorative glassware. It can neutralize discoloring impurities such as ferric ions and produce a neutral gray shade. It is used in a variety of glass products for this purpose. It is particularly useful as an amplifier for fiber optic data transfer. Erbium was first discovered by Carl Mosander in 1843. Erbium is named after the Swedish town, Ytterby. See Erbium research below.

Arsenic(As) atomic and molecular weight, atomic number and elemental symbolArsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3.Elemental Arsenic The arsenic atom has a radius of 124.5.pm and it's Van der Waals radius is 185.pm. Arsenic in the organic form is not harmful but in the inorganic form it is extremely toxic even in very small amounts. Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenidea. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot. Due to its toxicity, arsenic compounds are used in insecticides and wood preservation.Arsenic is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in Arsenic Bohr Modelthe form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Arsenic information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. See Arsenic research below.

An arsenide, an anion with the charge -3, is a rare mineral group consisting of compounds of one or more metals with arsenic (As). Arsenide anions have no existence in solution since they are extremely basic. These solid salts have very high lattice energies and are toxic due to the inherent toxicity of arsenic. Arsenides have applications in semiconductors, laser and light-emitting diodes, quantum dots, and optical and pressure sensors.
