Van der Waals radius is larger than the covalent radius, what is the reason behind this fact?
Van der Waals radius is larger than the covalent radius, what is the reason behind this fact?
The Van der Waals forces of attraction are weak. Thus, in case of atoms held by Van der Waal forces, the internuclear distance is much larger than those between covalently bonded atoms. Since, in a covalent bond a part of an electron cloud becomes common because it is formed by the overlapping of two half-filled atomic orbitals. Therefore, covalent radii are always less than the van der Waal radius.
