The single bond radius is the radius of an atom that is part of a covalent bond.


The bond lengths are measured by X-ray diffraction or by rotational spectroscopy.

If the atoms forms diatomic molecules, the covalent bond length is half the distance between the two nuclei.


Chemists usually obtain an average value from a variety of covalent compounds.

Hence, the values of covalent radii in tables may differ a bit because the averages are taken from different sample groups.
