  2. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    Other types include the double bond, the triple bond, one- and three-electron bonds, the three-center two-electron bond and three-center four-electron bond. In non-polar covalent bonds, the electronegativity difference between the bonded atoms is small, typically 0 to 0.3.

  3. Intramolecular force - Wikipedia

    en.wikipedia.org/wiki/Intramolecular_force

    The classical model identifies three main types of chemical bonds — ionic, covalent, and metallic — distinguished by the degree of charge separation between participating atoms. [3] The characteristics of the bond formed can be predicted by the properties of constituent atoms, namely electronegativity.

  4. Molecule - Wikipedia

    en.wikipedia.org/wiki/Molecule

    AFM image of 1,5,9-trioxo-13-azatriangulene and its chemical structure. [3] A molecule is a group of two or more atoms that are held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions that satisfy this criterion.

  5. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    Intermediate kinds of bonding: A solid with extensive hydrogen bonding will be considered a molecular solid, yet strong hydrogen bonds can have a significant degree of covalent character. As noted above, covalent and ionic bonds form a continuum between shared and transferred electrons; covalent and weak bonds form a continuum between shared ...

  6. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    A covalent bond forming H 2 (right) where two hydrogen atoms share the two electrons. A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs.

  7. Chemical compound - Wikipedia

    en.wikipedia.org/wiki/Chemical_compound

    Chemical compounds have a unique and defined chemical structure held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, intermetallic compounds held together by metallic bonds, or the subset of chemical complexes that are ...

  8. Valence (chemistry) - Wikipedia

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

    Valence is generally understood to be the number of chemical bonds that each atom of a given chemical element typically forms. Double bonds are considered to be two bonds, triple bonds to be three, quadruple bonds to be four, quintuple bonds to be five and sextuple bonds to be six.

  9. Triple bond - Wikipedia

    en.wikipedia.org/wiki/Triple_bond

    A triple bond in chemistry is a chemical bond between two atoms involving six bonding electrons instead of the usual two in a covalent single bond. Triple bonds are stronger than the equivalent single bonds or double bonds , with a bond order of three.
