Thulium (III) oxide is a pale green solid compound, with the formula Tm2O3. It was first isolated in 1878 from an impure sample of erbia by
Per Teodor Cleve, who named it thulia. It can be prepared in the laboratory by burning thulium metal in air, or by decomposition
of their oxoacid salts, such as thulium nitrate.
Thulium is a chemical element with symbol Tm and atomic number 69. It is the thirteenth and antepenultimate (third-last)
element in the lanthanide series. Like the other lanthanides, the most common oxidation state is +3, seen in its oxide,
halides and other compounds. In aqueous solution, like compounds of other late lanthanides, soluble thulium
compounds form complexes with nine water molecules.
