The 7 pages that link to Covalent radius, each with the reason it gives.

• Atomic radiusCompared with: Its bonded-atom basis differs from nonbonded radius estimates.

• Van der Waals radiusCompared with: It estimates bonded atomic size, unlike the nonbonded separation used to define this radius.

• Bohr radiusCompared with: It describes bonding distances, not the hydrogen ground-state wavefunction’s length scale.

• Space-filling modelCompared with: It describes bonded distances, whereas this model convention uses van der Waals radii.
