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. Terbium is never found in nature as a free element, but it is ...
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,IV) oxide, occasionally called tetraterbium heptaoxide, has the formula Tb 4 O 7, though some texts refer to it as TbO 1.75. There is some debate as to whether it is a discrete compound, or simply one phase in an interstitial oxide system. Tb 4 O 7 is one of the main commercial terbium compounds, and the only such product ...
Infobox references. Terbium (III) oxalate is the oxalate of terbium with the chemical formula Tb 2 (C 2 O 4) 3. Its decahydrate can be obtained by reacting terbium (III) chloride and oxalic acid in an aqueous solution. [ 1] Its decahydrate gradually loses water when heated and becomes anhydrous. Continued heating obtains terbium (III,IV) oxide ...
Terbium(III) acetate is the acetate salt of terbium, with a chemical formula of Tb(CH 3 COO) 3. Physical properties 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 ...
Terbium bismuthide. Other cations. Gadolinium phosphide. Dysprosium phosphide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Terbium phosphide is an inorganic compound of terbium and phosphorus with the chemical formula TbP. [1][2]
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 ...
