  2. 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.

    Intermediate organization of covalent bonds: Regarding the organization of covalent bonds, recall that classic molecular solids, as stated above, consist of small, non-polar covalent molecules. The example given, paraffin wax, is a member of a family of hydrocarbon molecules of differing chain lengths, with high-density polyethylene at the long ...

  4. 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. [5]

  5. Network covalent bonding - Wikipedia

    en.wikipedia.org/wiki/Network_covalent_bonding

    Examples of network solids include diamond with a continuous network of carbon atoms and silicon dioxide or quartz with a continuous three-dimensional network of SiO 2 units. Graphite and the mica group of silicate minerals structurally consist of continuous two-dimensional sheets covalently bonded within the layer, with other bond types ...

    en.wikipedia.org/wiki/Molecule

    A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are termed shared pairs or bonding pairs , and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is termed covalent bonding .

  7. Quadruple bond - Wikipedia

    en.wikipedia.org/wiki/Quadruple_bond

    A quadruple bond is a type of chemical bond between two atoms involving eight electrons. This bond is an extension of the more familiar types of covalent bonds: double bonds and triple bonds. [1] Stable quadruple bonds are most common among the transition metals in the middle of the d-block, such as rhenium, tungsten, technetium, molybdenum and ...

    [9] [10] Hydrogen bonds are amongst the strong intermolecular interactions know other than ion-dipole interactions. [10] 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.

  9. Coordinate covalent bond - Wikipedia

    en.wikipedia.org/wiki/Coordinate_covalent_bond

    An example of a dative covalent bond is provided by the interaction between a molecule of ammonia, a Lewis base with a lone pair of electrons on the nitrogen atom, and boron trifluoride, a Lewis acid by virtue of the boron atom having an incomplete octet of electrons. In forming the adduct, the boron atom attains an octet configuration.
