  2. Beryllium hydride - Wikipedia

    en.wikipedia.org/wiki/Beryllium_hydride

    Unlike the other group 2 metals, beryllium does not react with hydrogen. [3] Instead, BeH 2 is prepared from preformed beryllium(II) compounds. It was first synthesized in 1951 by treating dimethylberyllium, Be(CH 3) 2, with lithium aluminium hydride, LiAlH 4. [4] Purer BeH 2 forms from the pyrolysis of di-tert-butylberyllium, Be(C[CH 3] 3) 2 ...

  3. 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 .

  4. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H 2 O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out ...

  5. Beryllium - Wikipedia

    en.wikipedia.org/wiki/Beryllium

    Binary compounds of beryllium(II) are polymeric in the solid state. BeF 2 has a silica-like structure with corner-shared BeF 4 tetrahedra. BeCl 2 and BeBr 2 have chain structures with edge-shared tetrahedra. Beryllium oxide, BeO, is a white refractory solid which has a wurtzite crystal structure and a thermal conductivity as high as some metals.

  6. Beryllium iodide - Wikipedia

    en.wikipedia.org/wiki/Beryllium_iodide

    Beryllium iodide is an inorganic compound with the chemical formula Be I 2. It is a hygroscopic white solid. The Be 2+ cation, which is relevant to salt-like BeI 2, is characterized by the highest known charge density (Z/r = 6.45), making it one of the hardest cations and a very strong Lewis acid. [4]

  7. Organoberyllium chemistry - Wikipedia

    en.wikipedia.org/wiki/Organoberyllium_chemistry

    Organoberyllium chemistry involves the synthesis and properties of organometallic compounds featuring the group 2 alkaline earth metal beryllium (Be). [2] The area remains less developed relative to the chemistry of other main-group elements , because Be compounds are toxic and few applications have been found.

  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. Tetrafluoroberyllate - Wikipedia

    en.wikipedia.org/wiki/Tetrafluoroberyllate

    The crystals can be formed by dissolving BeF 2 in water, adding HF and then glycine. When the solution is cooled triglycine tetrafluoroberyllate forms. Cs 2 BeF 4 and Tl 2 BeF 4 in the solution reduce growth on the 001 direction so that tabular shaped crystals of TGFB form. The thallium compound can cut growth on the 001 axis by 99%. [37]
