The low mass isotopes are very difficult to create. [13] The initial detection of 37 Sc and 38 Sc only resulted in the characterization of their mass excess. [14] [15] Scandium also has five nuclear isomers: the most stable of these is 44m2 Sc (t 1/2 = 58.6 h). [16]
Molar mass: 186.11 g/mol Appearance ... Scandium(III) sulfide is a chemical compound of scandium and sulfur with the chemical formula Sc 2 S 3. It is a yellow solid.
Scandium triiodide, also known as scandium iodide, is an inorganic compound with the formula ScI 3 and is classified as a lanthanide iodide. This salt is a yellowish powder. [ 1 ] It is used in metal halide lamps together with similar compounds, such as caesium iodide, because of their ability to maximize emission of UV and to prolong bulb life.
Chemical formula. Sc 2 (SO 4) 3 Molar mass: 378.09 g mol −1 ... Scandium sulfate is the scandium salt of sulfuric acid and has the formula Sc 2 (SO 4) 3.
Scandium(III) hydroxide is an inorganic compound with the chemical formula Sc(OH) 3, the trivalent hydroxide of scandium. It is an amphoteric compound. [2] It is slightly soluble in water, and its saturated solution (pH = 7.85) contains Sc(OH) 3 and a small amount of Sc(OH) + 2. The solubility of scandium(III) hydroxide in water is 0.0279 mol/L.
Chemical formula. ScN Molar mass: 58.963 Density: 4.4 g/cm 3: Melting point: ... It is composed of the scandium cation and the nitride anion.
Chemical formula. ScCl 3 Molar mass: 151.31 g/mol Appearance ... Scandium(III) chloride is the inorganic compound with the formula ScCl 3.
In all four halides, the scandium is 6-coordinated. They can be prepared by reacting scandium oxide or scandium hydroxide with the corresponding acid: [3] Sc(OH) 3 + 3 HX → ScX 3 + 3 H 2 O. The halides are Lewis acids; for example, ScF 3 dissolves in a solution containing excess fluoride ion to form [ScF 6] 3−. The coordination number 6 is ...
