Ytterbium (Yb) atomic and molecular weight, atomic number and elemental symbolYtterbium has 2 valency states, +2 and +3. Ytterbium Bohr ModelThe number of electrons in each of Ytterbium's shells is 2, 8, 18, 32, 8, 2 and its electron configuration is [Xe]4f14 6s2. In its elemental form, CAS 7440-64-4. ytterbium has a silvery-white color.The Ytterbium atom has a radius of 194 pm and its Van der Waals radius is unknown.Elemental Ytterbium On the periodic table, Ytterbium is a Block F, Group 3, Period 6 element. Ytterbium is found in monazite sand as well as the ores euxenite and xenotime. Ytterbium was first discovered by Jean de Marignac in 1878. The name Ytterbium originates after the name for the Swedish village of Ytterby.

Ytterbium is being applied to numerous fiber amplifier and fiber optic technologies and in various lasing applications. It has a single dominant absorption band at 985 in the infra-red making it useful in silicon photocells to directly convert radiant energy to electricity. Ytterbium metal increases its electrical resistance when subjected to very high stresses. This property is used in stress gauges for monitoring ground deformations from earthquakes and nuclear explosions. It is also used in thermal barrier system bond coatings on nickel, iron and other transitional metal alloy substrates. Ytterbium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). High Purity (99.999%) Ytterbium (Yb) Sputtering Target Elemental or metallic forms include pellets, rod, wire and granules for evaporation source material purposes. High Purity (99.999%) Ytterbium Oxide (Yb2O3) PowderYtterbium nanoparticles and nanopowders provide ultra-high surface area which nanotechnology research and recent experiments demonstrate function to create new and unique properties and benefits. Oxides are available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Ytterbium is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.

Ytterbium is considered to be fairly toxic. Safety data for Ytterbium and its compounds can vary widely depending on the form.
