hexagonal close-packed (hcp) (hP2) Terbium is a chemical element; it has the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable and ductile. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas.
Isotopes of terbium (65Tb) Naturally occurring terbium (65 Tb) is composed of one stable isotope, 159 Tb. Thirty-seven radioisotopes have been characterized, with the most stable being 158 Tb with a half-life of 180 years, 157 Tb with a half-life of 71 years, and 160 Tb with a half-life of 72.3 days. All of the remaining radioactive isotopes ...

Terbium(III) oxide, also known as terbium sesquioxide, is a sesquioxide of the rare earth metal terbium, having chemical formula Tb 2 O 3. It is a p-type semiconductor, which conducts protons, which is enhanced when doped with calcium. [3] It may be prepared by the reduction of Tb 4 O 7 in hydrogen at 1300 °C for 24 hours. [4] Tb 4 O 7 + H 2 ...
Terbium compounds are compounds formed by the lanthanide metal terbium (Tb). Terbium generally exhibits the +3 oxidation state in these compounds, such as in TbCl 3, Tb (NO 3) 3 and Tb (CH 3 COO) 3. Compounds with terbium in the +4 oxidation state are also known, such as TbO 2 and BaTbF 6. [ 1 ] Terbium can also form compounds in the 0, [ 2 ...
Terbium (III) acetate reacts with caesium carbonate to form a precipitation of terbium hydroxycarbonate, which reacts with excess caesium carbonate and dissolves again. The reaction was irradiated with ultraviolet light with a wavelength of 365 nm, which has the characteristic green light of terbium. The tetrahydrate of terbium acetate can lose ...
Terbium(III) iodate is an inorganic compound with the chemical formula Tb(IO 3) 3. It can be obtained by the reaction of terbium(III) periodate and periodic acid in water at 160 °C, [ 1 ] or by the hydrothermal reaction of terbium(III) nitrate or terbium(III) chloride and iodic acid at 200 °C .
