Covalent Radius Definition

Definition: The covalent radius refers to the size of atom that forms part of a covalent bond. Covalent radius is expressed in terms of picometers or angstroms. In theory, the sum of two covalent radii should equal the covalent bond length between two atoms, but in practice the length of the bond depends on the chemical environment.
