  2. Beryllium chloride - Wikipedia

    en.wikipedia.org/wiki/Beryllium_chloride

    Beryllium chloride is an inorganic compound with the formula BeCl 2. It is a colourless, hygroscopic solid that dissolves well in many polar solvents. Its properties are similar to those of aluminium chloride , due to beryllium 's diagonal relationship with aluminium .

  3. Hydration number - Wikipedia

    en.wikipedia.org/wiki/Hydration_number

    One such approach counts the number of water molecules bound to the compound more strongly (by 13.3 kcal/mol or more) than they are bound to other water molecules. [3] Hydration number estimates are not limited to integer values (for instance, estimates for sodium include 4, 4.6, 5.3, 5.5, 5.6, 6, 6.5, and 8), with some of the spread of ...

  4. Solubility table - Wikipedia

    en.wikipedia.org/wiki/Solubility_table

    The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.

  5. Solvation shell - Wikipedia

    en.wikipedia.org/wiki/Solvation_shell

    A solvation shell or solvation sheath is the solvent interface of any chemical compound or biomolecule that constitutes the solute in a solution. When the solvent is water it is called a hydration shell or hydration sphere. The number of solvent molecules surrounding each unit of solute is called the hydration number of the solute.

  6. Solubility chart - Wikipedia

    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.

  7. List of CAS numbers by chemical compound - Wikipedia

    beryllium aluminate: 120041–06–7 Be(BH 4) 2: beryllium borohydride: 17440–85–6 BeB 2: beryllium boride: 12228–40–9 BeBr 2: beryllium bromide: 7787–46–4 Be(CHO 2) 2: beryllium formate: 1111–71–3 Be(C 2 H 3 O 2) 2: beryllium acetate: 543–81–7 Be(C 5 H 7 O 2) 2: beryllium acetylacetonate: 10210–64–7 BeCl 2: beryllium ...

  8. Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal

    Even the compound beryllium fluoride, which is the most ionic beryllium compound, has a low melting point and a low electrical conductivity when melted. [ 12 ] [ 13 ] [ 14 ] All the alkaline earth metals have two electrons in their valence shell, so the energetically preferred state of achieving a filled electron shell is to lose two electrons ...

  9. Metal ions in aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Metal_ions_in_aqueous_solution

    A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.
