  2. Beryllium - Wikipedia

    en.wikipedia.org/wiki/Beryllium

    Beryllium(II) forms many complexes with bidentate ligands containing oxygen-donor atoms. [52] The species [Be 3 O(H 2 PO 4) 6] 2-is notable for having a 3-coordinate oxide ion at its center. Basic beryllium acetate, Be 4 O(OAc) 6, has an oxide ion surrounded by a tetrahedron of beryllium atoms.

  4. Ionic radius - Wikipedia

    en.wikipedia.org/wiki/Ionic_radius

    Relative radii of atoms and ions. The neutral atoms are colored gray, cations red, and anions blue. Ions may be larger or smaller than the neutral atom, depending on the ion's electric charge. When an atom loses an electron to form a cation, the other electrons are more attracted to the nucleus, and the radius of the ion gets smaller.

  5. Metal ions in aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Metal_ions_in_aqueous_solution

    The strength of the M-O bond tends to increase with the charge and decrease as the size of the metal ion increases. In fact there is a very good linear correlation between hydration enthalpy and the ratio of charge squared to ionic radius, z 2 /r. [4] For ions in solution Shannon's "effective ionic radius" is the measure most often used. [5]

  6. Electric charge - Wikipedia

    en.wikipedia.org/wiki/Electric_charge

    An ion is an atom (or group of atoms) that has lost one or more electrons, giving it a net positive charge (cation), or that has gained one or more electrons, giving it a net negative charge (anion). Monatomic ions are formed from single atoms, while polyatomic ions are formed from two or more atoms that have been bonded together, in each case ...

  7. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    Atomic numbers (Z) are a special case of charge numbers, referring to the charge number of an atomic nucleus, as opposed to the net charge of an atom or ion. The charge numbers for ions (and also subatomic particles ) are written in superscript, e.g., Na + is a sodium ion with charge number positive one (an electric charge of one elementary ...

  8. 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 ]

  9. Beryllium sulfate - Wikipedia

    en.wikipedia.org/wiki/Beryllium_sulfate

    Beryllium sulfate normally encountered as the tetrahydrate, [Be(H 2 O) 4]SO 4 is a white crystalline solid. It was first isolated in 1815 by Jons Jakob Berzelius . [ 4 ] Beryllium sulfate may be prepared by treating an aqueous solution of many beryllium salts with sulfuric acid , followed by evaporation of the solution and crystallization.
