About Thulium(III) Oxalate

Oxalate IonAnhydrous Thulium(III) Oxalate is highly insoluble in water and converts to the oxide when heated (calcined). Thulium(III) Oxalate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Thulium emits blue upon excitation in flat panel screens and under X-ray bombardment emits both the 375 nm (ultra violet) and 465 (visible blue) wave lengths giving it useful applications in low radiation detection for detection badges and similar uses. 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.

Thulium Bohr ModelThe number of electrons in each of Thulium's shells is [2, 8, 18, 31, 8, 2] and its electron configuration is [Xe]4f136s2. The thulium atom has a radius of 176 pm and a Van der Waals radius of 227 pm.Elemental Thulium Picture In its elemental form, thulium has a silvery-gray appearance. Thulium is representative of the other lanthanides (rare earths) and similar in chemistry to yttrium. It is the least abundant of the rare earth elements. Thulium emits blue upon excitation, and is used in flat panel screens that depend critically on bright blue emitters. Thulium was discovered and first isolated by Per Teodor Cleve in 1879. It is named after "Thule," which is the ancient name of Scandinavia.
