Rubidium is the 18th most abundant element in seawater. [15]: 371 Because of its large ionic radius, rubidium is one of the "incompatible elements". [34] During magma crystallization, rubidium is concentrated together with its heavier analogue caesium in the liquid phase and crystallizes last.
Rubidium oxide is the chemical compound with the formula Rb 2 O. Rubidium oxide is highly reactive towards water, and therefore it would not be expected to occur ...
Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice .
These are compounds that include rubidium, most possibly in +1 ion form. Pages in category "Rubidium compounds" The following 34 pages are in this category, out of 34 ...
Rubidium iodide is a salt of rubidium and iodine, with the chemical formula RbI. It is a white solid with a melting point of 642 °C. Preparation ...
In addition to simple rubidium fluoride, an acidic rubidium fluoride with the molecular formula HRbF 2 is also known, [4] which can be produced by reacting rubidium fluoride and hydrogen fluoride. [4] The compounds H 2 RbF 3 and H 3 RbF 4 were also synthesized. [5] [4] The solubility in acetone is 0.0036 g/kg at 18 °C and 0.0039 g/kg at 37 °C ...
Ion Reactivity Extraction Caesium Cs Cs + reacts with cold water Electrolysis (a.k.a. electrolytic refining) Rubidium Rb Rb + Potassium K K + Sodium Na Na + Lithium Li Li + Barium Ba Ba 2+ Strontium Sr Sr 2+ Calcium Ca Ca 2+ Magnesium Mg Mg 2+ reacts very slowly with cold water, but rapidly in boiling water, and very vigorously with acids ...
Rubidium hydroxide is the inorganic compound with the formula RbOH. It consists of rubidium cations and an equal number of hydroxide anions. It is a colorless solid that is commercially available as aqueous solutions from a few suppliers. Like other strong bases, rubidium hydroxide is highly caustic. Rubidium hydroxide is formed when rubidium ...
