  2. Rubidium bromide - Wikipedia

    en.wikipedia.org/wiki/Rubidium_bromide

    Rubidium bromide is an inorganic compound with the chemical formula Rb Br. It is a salt of hydrogen bromide. It consists of bromide anions Br − and rubidium cations Rb +. It has a NaCl crystal structure, with a lattice constant of 685 picometres. [1] There are several methods for synthesising rubidium bromide.

    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.

  4. Ion association - Wikipedia

    en.wikipedia.org/wiki/Ion_association

    In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...

    A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [ 3 ]

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  8. Ionic radius - Wikipedia

    en.wikipedia.org/wiki/Ionic_radius

    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.

    Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...
