  2. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    As noted above, covalent and ionic bonds form a continuum between shared and transferred electrons; covalent and weak bonds form a continuum between shared and unshared electrons. In addition, molecules can be polar, or have polar groups, and the resulting regions of positive and negative charge can interact to produce electrostatic bonding ...

  3. Van Arkel–Ketelaar triangle - Wikipedia

    en.wikipedia.org/wiki/Van_Arkel–Ketelaar_triangle

    Rather, bond types are interconnected and different compounds have varying degrees of different bonding character (for example, covalent bonds with significant ionic character are called polar covalent bonds). Six years later, in 1947, Ketelaar developed van Arkel's idea by adding more compounds and placing bonds on different sides of the triangle.

  4. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    4 or SO 2− 4. In simpler words, an ionic bond results from the transfer of electrons from a metal to a non-metal to obtain a full valence shell for both atoms. Clean ionic bonding — in which one atom or molecule completely transfers an electron to another — cannot exist: all ionic compounds have some degree of covalent bonding or

  5. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    Ionic bonding is a type of electrostatic interaction between atoms that have a large electronegativity difference. There is no precise value that distinguishes ionic from covalent bonding, but an electronegativity difference of over 1.7 is likely to be ionic while a difference of less than 1.7 is likely to be covalent. [21] Ionic bonding leads ...

  6. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    [2] [3] The term covalent bond dates from 1939. [4] The prefix co-means jointly, associated in action, partnered to a lesser degree, etc.; thus a "co-valent bond", in essence, means that the atoms share "valence", such as is discussed in valence bond theory. In the molecule H 2, the hydrogen atoms share the two electrons via covalent bonding ...

  7. Salt (chemistry) - Wikipedia

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

    The circumstances under which a compound will have ionic or covalent character can typically be understood using Fajans' rules, which use only charges and the sizes of each ion. According to these rules, compounds with the most ionic character will have large positive ions with a low charge, bonded to a small negative ion with a high charge. [25]

  8. Partial charge - Wikipedia

    en.wikipedia.org/wiki/Partial_charge

    the Extended Born thermodynamic cycle, including an analysis of covalent and ionic bonding contributions; spectroscopically measured properties, such as core-electron binding energy shifts; the relationship of atomic charges to melting points, solubility, and cleavage energies for a set of similar compounds with similar degree of covalent bonding

  9. Cross-link - Wikipedia

    en.wikipedia.org/wiki/Cross-link

    In chemistry and biology, a cross-link is a bond or a short sequence of bonds that links one polymer chain to another. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic polymers or natural polymers (such as proteins ).
