  2. Beryllium hydride - Wikipedia

    en.wikipedia.org/wiki/Beryllium_hydride

    BeH 2 is usually formed as an amorphous white solid, but a hexagonal crystalline form with a higher density (~0.78 g/cm 3) was reported, [7] prepared by heating amorphous BeH 2 under pressure, with 0.5-2.5% LiH as a catalyst. Subunit of structure of BeH 2. Each Be is tetrahedral and each H is doubly bridging. [8]

  3. Beryllium fluoride - Wikipedia

    en.wikipedia.org/wiki/Beryllium_fluoride

    Beryllium fluoride has distinctive optical properties. In the form of fluoroberyllate glass, it has the lowest refractive index for a solid at room temperature of 1.275. Its dispersive power is the lowest for a solid at 0.0093, and the nonlinear coefficient is also the lowest at 2 × 10 −14.

  4. Beryllium chloride - Wikipedia

    The other form resembles zinc iodide with interconnected adamantane-like cages. [4] In contrast, BeF 2 is a 3-dimensional polymer, with a structure akin to that of quartz. In the gas phase, BeCl 2 exists both as a linear monomer and a bridged dimer with two bridging chlorine atoms where the beryllium atom is 3-coordinate. [5]

  5. Beryllium - Wikipedia

    In the solid state, the hydroxyl group may deprotonate: a hexamer, Na 4 [Be 6 (OCH 2 (O)O) 6], was isolated long ago. [54] [55] Aromatic hydroxy ligands (i.e. phenols) form relatively strong complexes. For example, log K 1 and log K 2 values of 12.2 and 9.3 have been reported for complexes with tiron. [54] [56]

  6. Beryllium oxide - Wikipedia

    en.wikipedia.org/wiki/Beryllium_oxide

    Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond, and exceeds that of most metals. [12]

  7. Solid solution - Wikipedia

    en.wikipedia.org/wiki/Solid_solution

    The propensity for any two substances to form a solid solution is a complicated matter involving the chemical, crystallographic, and quantum properties of the substances in question. Substitutional solid solutions, in accordance with the Hume-Rothery rules, may form if the solute and solvent have: Similar atomic radii (15% or less difference)

    This table lists only the occurrences in compounds and complexes, not pure elements in their standard state or allotropes. Noble gas +1 Bold values are main oxidation states

  9. Chemical state - Wikipedia

    en.wikipedia.org/wiki/Chemical_state

    The chemical state of a group of elements, can be similar to, but not identical to, the chemical state of another similar group of elements because the two groups have different ratios of the same elements and exhibit different chemical, electronic, and physical properties that can be detected by various spectroscopic techniques.
