  2. Bond length - Wikipedia

    en.wikipedia.org/wiki/Bond_length

    It is generally considered the average length for a carbon–carbon single bond, but is also the largest bond length that exists for ordinary carbon covalent bonds. Since one atomic unit of length (i.e., a Bohr radius) is 52.9177 pm, the C–C bond length is 2.91 atomic units, or approximately three Bohr radii long.

  4. Atomic spacing - Wikipedia

    en.wikipedia.org/wiki/Atomic_spacing

    Bond length can be determined between different elements in molecules by using the atomic radii of the atoms. Carbon bonds with itself to form two covalent network solids. [2]

  5. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometries can be specified in terms of 'bond lengths', 'bond angles' and 'torsional angles'. The bond length is defined to be the average distance between the nuclei of two atoms bonded together in any given molecule. A bond angle is the angle formed between three atoms across at least two bonds.

    en.wikipedia.org/wiki/Atomic_units

    The distances relevant to the physics expressed in SI units are naturally on the order of ⁠ ⁠, while expressed in atomic units distances are on the order of ⁠ ⁠ (one Bohr radius, the atomic unit of length). An additional benefit of expressing quantities using atomic units is that their values calculated and reported in atomic units do ...

  8. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The picometre (SI symbol: pm) is a unit of length in the metric system equal to 10 −12 metres (⁠ 1 / 1 000 000 000 000 ⁠ m = 0. 000 000 000 001 m). To help compare different orders of magnitude this section lists lengths between 10 −12 and 10 −11 m (1 pm and 10 pm). 1 pm – distance between atomic nuclei in a white dwarf [citation ...

  9. Picometre - Wikipedia

    en.wikipedia.org/wiki/Picometre

    The picometre's length is of an order so small that its application is almost entirely confined to particle physics, quantum physics, chemistry, and acoustics. Atoms are between 62 and 520 pm in diameter, and the typical length of a carbon–carbon single bond is 154 pm. Smaller units still may be used to describe smaller particles (some of which are the components of atoms themselves), such ...
