Bond length
The bond length is the measured core-to- core distance between two atoms or ions in chemical bonds.
Chemistry
In crystalline solids with ions or metal mesh, the spacing of the lattice elements by X-ray or electron diffraction can be determined. As in crystal lattices of different distances of the power levels can be measured in the tables in general, the minimum distance is given as bond length.
In calcium fluoride, the distance between calcium cations Ca2 and the fluoride anion is F -235 pm (1 pm = 10-12 m). In metal grids, the distance depending on the atomic size between 200 pm and 500 pm. For a carbon- carbon bond (single), this distance is about 154 pm.
For bond lengths of atomic bonds see there.
Hydrogen bonds vary significantly according to degree of polarization distances between 120 pm and 300 pm on.
