  2. Phosphorus halide - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_halide

    Phosphorus(II) halides may be prepared by passing an electric discharge through a mixture of the trihalide vapour and hydrogen gas. [citation needed] The relatively stable P 2 I 4 is known to have a trans, bent configuration similar to hydrazine and finds some uses in organic syntheses, the others are of purely academic interest at the present ...

  3. Molecular solid - Wikipedia

    en.wikipedia.org/wiki/Molecular_solid

    For intermolecular hydrogen bonds the δ+ hydrogen interacts with a δ- on an adjacent molecule. Examples of molecular solids that hydrogen bond are water, amino acids , and acetic acid. [ 3 ] [ 5 ] [ 8 ] [ 10 ] For acetic acid, the hydrogen (δ+) on the alcohol moiety of the carboxylic acid hydrogen bonds with other the carbonyl moiety (δ ...

  4. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    A large molecule with an ionized group is technically an ion, but its behavior may be largely the result of non-ionic interactions. For example, sodium stearate (the main constituent of traditional soaps) consists entirely of ions, yet it is a soft material quite unlike a typical ionic solid. There is a continuum between ionic solids and ...

  5. Hydron (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Hydron_(chemistry)

    In chemistry, the hydron, informally called proton, [2] is the cationic form of atomic hydrogen, represented with the symbol H +The general term "hydron", endorsed by IUPAC, encompasses cations of hydrogen regardless of isotope: thus it refers collectively to protons (1 H +) for the protium isotope, deuterons (2 H + or D +) for the deuterium isotope, and tritons (3 H + or T +) for the tritium ...

  6. Dihydrogen cation - Wikipedia

    en.wikipedia.org/wiki/Dihydrogen_cation

    The ion can be formed from the ionization of a neutral hydrogen molecule by electron impact. It is commonly formed in molecular clouds in space by the action of cosmic rays . The dihydrogen cation is of great historical, theoretical, and experimental interest.

  7. Binary compounds of hydrogen - Wikipedia

    en.wikipedia.org/wiki/Binary_compounds_of_hydrogen

    Binary hydrogen compounds in group 1 are the ionic hydrides (also called saline hydrides) wherein hydrogen is bound electrostatically. Because hydrogen is located somewhat centrally in an electronegative sense, it is necessary for the counterion to be exceptionally electropositive for the hydride to possibly be accurately described as truly behaving ionic.

  8. Phosphoric acids and phosphates - Wikipedia

    en.wikipedia.org/wiki/Phosphoric_acids_and...

    The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and ⁠ n + 2 / 2 ⁠. Pyrophosphate anion. Trimethyl ...

  9. Hydrogen ion cluster - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_ion_cluster

    6 can migrate through solid hydrogen by linking a hydrogen molecule at one end and losing it at the other: H 2 + H + 6 → H + 6 + H 2. This migration stops once an HD molecule is added resulting in a lower energy level. [3] HD or D 2 is added in preference over H 2. [4] Clampitt and Gowland found clusters with an odd number of hydrogen atoms H ...
