Ytterbium has 2 valency state, +2 +3. The number of electrons in each of Ytterbium's shells is 2, 8, 18, 32, 8, 2 and its electronic configuration is [Xe]4f14 6s2. In its metallic form Ytterbium's CAS number is 7440-64-4 and its standard state at 20 şC is a solid. The Ytterbium atom has a radius of 194 pm and it's Van der Waals radius is unknown. Ytterbium is considered to be fairly toxic. On the periodic table, Ytterbium is a Block F, Group 3, Period 6 element. Ytterbium isbeing applied to numerous fiber amplifier and fiber optic technologies and in various lasing applications. Ytterbium is available 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. 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.The name Ytterbium originates after the name for the Swedish village of Ytterby. See Ytterbium research below.
Yttrium is a Block D, Group 3, Period 5 element. The number of electrons in each of Yttrium's shells is 2, 8, 18, 9, 2 and its electronic configuration is [Kr] 4d1 5s2. In its elemental form Yttrium's CAS number is 7440-65-5. The yttrium atom has a radius of 177.6.pm and it's Van der Waals radius is 200.pm. Insoluble compounds of Yttrium are non-toxic, although water soluble compounds are somewhat toxic. Yttrium has the highest thermo-dynamic affinity for oxygen of any element. This characteristic is the basis for many of its applications. While not part of the rare earth series, it resembles the heavy rare earths which are sometimes referred to as the “yttrics” for this reason. Another unique characteristic derives from its ability to form crystals with useful properties. Yttrium is available 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 assubmicron and nanopowder. Some of the many applications of yttrium include in ceramics for crucibles for molten reactive metals, in florescent lighting phosphors, computer displays and automotive fuel consumption sensors.Yttria stabilized zirconium oxide are used in high temperature applications, such as in thermal plasma sprays to protect aerospace high temperature surfaces and as an electrolyte in solid oxide fuel cells. The name Yttrium originated from a Swedish village near Vaxholm called Yttbery where Yttrium was discovered. Crystals of the yttrium-iron-garnet (YIG) variety are essential to microwave communication equipment. The phosphor Eu:Y2O2S creates the red color in televisions. Crystals of the yttrium-aluminum-garnet (YAG) variety are utilized with neodymium in a number of laser applications. Yttria can also increase the strength of metallic alloys. Yttrium was first discovered by Johann Gadolin in 1794. See Yttrium research below..
Vanadium is a Block D, Group 5, Period 4 element. The number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electronic configuration is [Ar] 3d3 4s2. In its elemental form vanadium's CAS number is 7440-62-2. The vanadium atom has a radius of 131.1.pm and it's Van der Waals radius is 200.pm. Several vanadium compounds are toxic to some creatures despite the fact that it is an essential trace element. Vanadium is highly resistant to corrosion, so it is commonly used to alloy stainless steel grades. Vanadium compounds are used in advanced ceramics. Vanadium is a petrochemical cracking catalyst. Vanadium is available 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. Vanadium 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. Vanadium was first discovered in Mexico City by Andres Manuel del Rio, a Spanish born and European educated Mexican mineralogist, in 1801. In honor of its beautiful multi-colored compounds, Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology. See Vanadium research below.

Yttrium is a Block D, Group 3, Period 5 element. The number of electrons in each of Yttrium's shells is 2, 8, 18, 9, 2 and its electronic configuration is [Kr] 4d1 5s2. In its elemental form Yttrium's CAS number is 7440-65-5. The yttrium atom has a radius of 177.6.pm and it's Van der Waals radius is 200.pm. Insoluble compounds of Yttrium are non-toxic, although water soluble compounds are somewhat toxic. Yttrium has the highest thermo-dynamic affinity for oxygen of any element. This characteristic is the basis for many of its applications. While not part of the rare earth series, it resembles the heavy rare earths which are sometimes referred to as the “yttrics” for this reason. Another unique characteristic derives from its ability to form crystals with useful properties. 
Yttrium is available 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. Some of the many applications of yttrium include in ceramics for crucibles for molten reactive metals, in florescent lighting phosphors, computer displays and automotive fuel consumption sensors.Yttria stabilized zirconium oxide are used in high temperature applications, such as in thermal plasma sprays to protect aerospace high temperature surfaces and as an electrolyte in solid oxide fuel cells. The name Yttrium originated from a Swedish village near Vaxholm called Yttbery where Yttrium was discovered. Crystals of the yttrium-iron-garnet (YIG) variety are essential to microwave communication equipment. The phosphor Eu:Y2O2S creates the red color in televisions. Crystals of the yttrium-aluminum-garnet (YAG) variety are utilized with neodymium in a number of laser applications. Yttria can also increase the strength of metallic alloys. Yttrium was first discovered by Johann Gadolin in 1794. See Yttrium research below..
